2.8 Problems and Solutions (FAQ)

  • Insure backups are completed before doing the upgrade
    1. See WordPress Backups

    Can’t login to deactivate all plugins
    1. Read How to deactivate all plugins when not able to access the administrative menus?

    Try these things to resolve problems with Visual Editor and editor tool bar
    1. Delete or refresh the browser cache

    2. If using Gears, disable it and re-enable it again

    3. Delete wp-admin and wp-includes directories and upload fresh copies from a new(important) install package or reinstall automatically

    4. Visit http://yoursite.com/wp-includes/js/tinymce/wp-tinymce.php and look for any PHP errors or warnings at the top. If there are any try contacting your hosting provider to resolve them or try the next step. Of course replace yoursite.com with your domain

    5. A number of plugins have been reported to present problems so deactivate all plugins and reactivate one-by-one to find culprit. Any plugin that uses its own javascripts might be a possible candidate.

    6. Add define( ‘CONCATENATE_SCRIPTS’, false ); near the top of wp-config.php. That would make WordPress admin run slower, so can try removing it in a few days and testing again (this would eliminate any stale network cache)

    7. Some people also reported success redoing the upgrade via Tools->Upgrade->Re-install automatically, then clearing the browser cache.

    8. Try another browser

    9. Confirm that Your Profile, “Disable the visual editor when writing”, is NOT checked.

    Try these things to resolve problems with Widgets such as not able to drag and drop
    1. A number of plugins have been reported to present problems so deactivate all plugins and reactivate one-by-one to find culprit

    2. In Appearance->Widgets under Screen options, try the Enable Accessibility Mode

    3. Delete or refresh the browser cache

    Fatal error: Allowed memory size of xxxxxxxx bytes exhausted
    If deactivating plugins doesn’t work try one of these methods for increasing the amount of memory a PHP script may consume

    1. If you have access to your PHP.ini file, change the line in PHP.ini
    If your line shows 32M try 64M:
    memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

    2. If you don’t have access to PHP.ini try adding this to an .htaccess file:
    php_value memory_limit 64M

    3. Try adding this line to your wp-config.php file:
    Increasing memory allocated to PHP
    define('WP_MEMORY_LIMIT', '64M');

    4. Talk to your host.

    FYI when I upgraded to 2.8 my permissions to log in were gone. I had to call my host so they could set them back to 755

    For some reason this thread is not showing up as a sticky. Someone should fix that as many, many people are having problems.

    I loaded a tester wp set-up to test a new theme, using the new upgrade for wp and it was working fine…then suddenly blank page. Deactivated the 1 plugin I had and still nothing…

    Any other ideas…so frustrating!

    For those who are having a problem in the admin panel (ajax/JS not working), it could be because of the category icon plugin. If you are using that, you might want to check this out:

    =) Happy blogging y’all!

    My situation is a bit odd. I have managed to get 2.8 working with plugins that do not conflict. My problem now is that any time one of the working plug ins is upgraded, it makes the “Other News” box on home page and sometimes it removes the time option and save button from the general settings page. After each plugin upgrade, I have to go back in, deactivate all plug ins and reactivate them again.

    Any ideas what could be causing this? I’m kinda like ????? Simply because I have everything working perfectly and when i upgrade any plugin this happens. So weird.

    Thank you!

    I think it was 2.7 that caused a problem when I tried to register a MaxBlogPress plugin that I needed. I used ftp to downgade back to the previous version, registered the plugin, and then upgraded again. Worked fine. (Believe I left the wp-config.php file and wp-content folder unchanged.)

    Just as I caught onto html…php came out, so I guess I’m an experienced novice. I”m curious…

    With all the problems everyone seems to be having with 2.8, wouldn’t it be just as easy to downgrade back to 2.7.1 and wait a couple of weeks until the inevitable bug-fixed 2.8.1 version is released?

    I found two problems by going through the deactivation of all the plug-ins and reactivating them one by one.

    The one was a wayward plug in that when I got that out of the way, then I found my simplepie problem. Simplepie, for those who need a reminder like I did, powers news feeds. The problem was with the SimplePie core, which I discovered would not work with 2.8 But fortunately by typing SimplePie into the plug in search, I found that there is now a specific WordPress SimplePie plugin that does not crash when activated.

    I hope this helps someone. Really do go through each of the Plug-ins, it helps. De-activate all your plug-ins. Then starting at the top, Activate one and then click on the help tab. If help opens, that plug in is ok. Move on to the next plug-in and repeat.

    Thanks so much to all of the friendly and patient members and moderators. All of this is so much better when we leave out our frustration with ourselves, and with beginners like me.

    Hi,
    The issue I’ve noticed with 2.8 pertains to categories and posts. Late last night while adding tags to a post, I noticed after publishing that one of my tags is also now listing in the categories. I’ve deleted the tag/category and re-added it and it still displays as both a tag a category. How do I correct this and get my tag to only display as a tag?

    I upgraded to 2.8 and my blog site reverted to blogs posted on 4-17-2009, later blogs are given thier own page id and i can only find them through the dashboard. To put them on the front of the blog I have to check stick on front page. But they still don’t go in any order. Please help?

    @figaro

    Is it possible to downgrade from 2.8 back to 2.7.1? Part of the upgrade procedure is some modification of the database.

    Honestly, it seems like it might be easier for me to downgrade any sites that are having problems and wait for new versions of the plugins to come out than to try to fix them.

    Thanks

    Here’s a little humor. The 2.8 download is still available…lol ha. It’s on the wordpress.org page. Funny joke ha. Not

    I used to love working with WordPress, but absolutely hate 2.8! Can’t see anything in the visual editor, and it takes twice as long to drag ‘n drop the widgets as it did with the “add widget” link. Absolutely horrible!! May end up downgrading all of my blogs back to 2.7.1 and never upgrading again.

    Yes, Minnow…you can downgrade. Leave your wp-config.php file and wp-content folder untouched. Deactivate all your plugins first. When I downgraded, I made no changes or modifications to the database. Worked fine.

    Thanks larry…but i am newbie…I know how to deactivate my plugins…but how do i downgrade from there?
