Can’t go to the WP dashboard because installation hasn’t finished. wp-cli can’t help because the dashboard isn’t available. Is your plugin version a string in one of the files? * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Duplicator - Backups & Migration Plugin - Cloud Backups, Scheduled Backups, & More] SESSION variable ‘max_allowed_packet’ is read-only](https://wordpress.org/support/topic/session-variable-max_allowed_packet-is-read-only/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [4 years, 2 months ago](https://wordpress.org/support/topic/session-variable-max_allowed_packet-is-read-only/#post-15416651) * As an experiment I commented out line 60. Line 85 also required ‘GLOBAL’. With these 2 changes the installer completed successfully. Hopefully the installation isn’t hosed, at least according to the installer there were no problems (with these fixes in place). * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Duplicator - Backups & Migration Plugin - Cloud Backups, Scheduled Backups, & More] installer broken – check collation capability incorrect](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [4 years, 2 months ago](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/#post-15416430) * Your workaround solves the problem, thank you.

I’ll give that a try. I opened a ticket just to make sure this issue gets tracked. I think the fixes I proposed will work just fine – I assumed it’s just a matter of constructing a correct collation list when the archive is built and your suggested workaround indicates that this is the case. - This reply was modified 4 years, 2 months ago by [nbi1](https://wordpress.org/support/users/nbi1/). * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Duplicator - Backups & Migration Plugin - Cloud Backups, Scheduled Backups, & More] installer broken – check collation capability incorrect](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [4 years, 2 months ago](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/#post-15413621) * Figured it out. My instincts about an incorrect check were on target – the installer is indeed performing an invalid check. * During the backup of the original you execute the above query to get the list of collations. That’s fine. But when you store the list in the installer you store utf8_general_ci when in fact utf8_general_ci does not appear in the query result! Why? Because you find utf8mb3_general_ci which is an alias for utf8_general_ci and you unalias before storing the list. So at the restore end of the operation the installer consults the list which includes utf8_general_ci and the validation fails because it’s not found in the server collation list. But it is there – as the alias utf8mb3_general_ci ! Actually the installer hints at this problem with its output – it should not be showing utf8_general_ci it should show utf8mb3_general_ci because the aliased form is used in newer versions of MariaDB (I didn’t know that until I researched this issue). * So the fix consists of 2 checks when backing up: 1. If the collation query returns utf8mb3_general_ci store that – do not store the unaliased utf8_general_ci. 2. If the collation query returns utf8_general_ci (old MariaDB) store the alias utf8mb3_general_ci instead. * These checks will ensure that with a newer (older doesn’t make sense) MariaDB the installer will properly try to match utf8mb3_general_ci in its list against utf8mb3_general_ci in the server collation list. * This fix will solve the problem for anyone going through the backup/restore cycle for the first time. It won’t help those like me who already have an installer backup set with utf8_general_ci instead of utf8mb3_general_ci. Couple of possible solutions for that: 1. a standalone tool/script that fixes the installer’s collation list, or 2. add installer option to handle this case (can’t just omit this validation because if utf8mb3_general_ci is missing from the server then there is a real problem). Manually hacking the installer list would probably work if I knew where it was buried, but I’m sure you don’t want the headaches resulting from asking users to do this. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Duplicator - Backups & Migration Plugin - Cloud Backups, Scheduled Backups, & More] installer broken – check collation capability incorrect](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [4 years, 2 months ago](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/#post-15413215) * Sorry, didn’t see your response when I posted – disregard my last post. Based on your response I have a theory on what might be going on, but I’ll need to do some testing to confirm. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Duplicator - Backups & Migration Plugin - Cloud Backups, Scheduled Backups, & More] installer broken – check collation capability incorrect](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [4 years, 2 months ago](https://wordpress.org/support/topic/installer-broken-check-collation-capability-incorrect/#post-15413195) * My guess is that the bug consists of just looking for ‘utf8’ to infer which collations are needed. This wouldn’t be a problem with older versions of MariaDB (pre 10.6.4?) because these older server versions still included utf8/utf8_general_ci. So even if utf8 is erroneously flagged as needed it’ll still get past the installer because the server supports it. But the newer versions (10.6.4+) do not so the bug is exposed. Googling shows numerous reports about the MariaDB utf8 problem, this is typical: [https://www.mail-archive.com/misc@openbsd.org/msg179329.html](https://www.mail-archive.com/misc@openbsd.org/msg179329.html). If my guess is correct the fix should be simple – don’t look for ‘utf8’, look for ‘utf8mb4’. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Duplicator - Backups & Migration Plugin - Cloud Backups, Scheduled Backups, & More] PHP 8.1 Compatibility…](https://wordpress.org/support/topic/php-8-1-compatibility-2/) * [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [4 years, 2 months ago](https://wordpress.org/support/topic/php-8-1-compatibility-2/#post-15410225) * The plugin might be 8.1 compatible, but installer.php is not. * /var/log/apache2/error.log: [Mon Feb 28 00:04:57.016844 2022] [php:error] [pid 24518] [client 192.168.1.5:50674] PHP Fatal error: Array and string offset access syntax with curly braces is no longer supported in /var/www/html/installer.php on line 632 * I had backed up my WP installation over a year ago and only recently attempted a restore when I encountered this.

I just found one of your tutorials on featured image which seems to contain code for extracting the first found article image as the featured. I’ll give that a try. * Regarding the display of the image I may have misunderstood something in the docs. I took image_size=”thumbnail” to mean scale & display the featured image. It seemed to me that the presence of “image_size” would make include_image=”true” unnecessary since one wouldn’t use “image_size” unless the intent was to display the image. But based on your comment both are necessary if one wants to display a thumbnail? * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Display Posts - Easy lists, grids, navigation, and more] how to display post source?](https://wordpress.org/support/topic/how-to-display-post-source/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [6 years, 2 months ago](https://wordpress.org/support/topic/how-to-display-post-source/#post-12456534) * I’m using WPematico for feed aggregation. You are correct, a unique category for each source is a good solution. Another possibility is creating a unique campaign for each source. * The next 2 issues to grapple with are the publication dates of the articles in the posts (for which I can’t find a parameter) and setting an article image to be the featured image. * I’ll probably need to create a custom template as well, but I found a straightforward recipe for doing that so that won’t be an impediment. Regarding the publication date maybe I missed something while looking at the parameter listing. It just seems like that would be a commonly used data item to be displayed. * Many thanks. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[WPeMatico RSS Feed Fetcher] set featured image not working](https://wordpress.org/support/topic/set-featured-image-not-working-17/) * Thread Starter [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [6 years, 2 months ago](https://wordpress.org/support/topic/set-featured-image-not-working-17/#post-12452035) * I aggregate multiple feeds and I checked the page source of the feed items – they definitely contain images ().

Duh. * There are however annoyingly large gaps between adjacent columns of the grid that I can’t seem to shrink even with your suggested CSS.

I forgot about the warnings involving the “featured image”. It’s easy to forget about that because if the post contains an embedded image it will display correctly via the single template. But as far as post grids go the “featured image” is *required*. I need to get into the habit of always setting the “featured image” even if it duplicates the embedded image. Since grids seem to require this I’m not sure why the default simply doesn’t set the“ featured image” using the first embedded image. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Display Posts - Easy lists, grids, navigation, and more] Grid not working anymore](https://wordpress.org/support/topic/grid-not-working-anymore/) * [nbi1](https://wordpress.org/support/users/nbi1/) * (@nbi1) * [6 years, 3 months ago](https://wordpress.org/support/topic/grid-not-working-anymore/#post-12374384) * Similar problem, but I can’t get your CSS to work.
