The essential add-on for the NextGEN Gallery WordPress plugin.
Please see the following page in Optimizer's documentation... http://www.nextgengalleryoptimizer.com/docs/limitations/
As of WordPress v4.2 (possibly earlier) the Sort Gallery page in the admin fails to save changes to the image sort order. It gives the following notice on-save when WP_DEBUG is active: "Notice: Undefined variable: sortArray in ...nextgen-gallery/admin/manage-sort.php on line 19". One workaround would be to simply upload your images in the order you want them displayed.
There are also a few new notices (when WP_DEBUG is active) in WordPress v4.3, however the widgets do still appear to be working: "Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use __construct() instead. in .../wp-includes/functions.php on line 3457".
There are many possibilities (typically ownership/permissions issues), but here's an odd one from personal experience. Hopefully it'll help...
I had created several development installs across numerous WordPress releases to test Optimizer with the latest NextGEN 2.0.xx version (v22.214.171.124 specifically), but NextGEN's image uploads weren't working on any of them. All file ownership and permissions were correct, but NextGEN's uploads page was just showing a yellow error triangle with a tooltip of "HTTP error".
If you're sure Fancybox is activated on Optimizer's settings page, and the lightbox still won't display using the "Use WordPress jQuery [greater compatibility]" setting, it is highly likely you have a conflict caused by two or more instances of jQuery loading on the same page. This is typically due to jQuery calls having been hard-coded into your theme.
Please inspect your theme files (the header.php and footer.php in particular) for lines including jquery.js or jquery.min.js and either comment them out, or remove them altogether.
Additionally, make sure you have wp_head(); in your theme's header.php file. It will usually be right before the closing </ head > tag, and is an essential hook for plugins such as Optimizer to be able to load the necessary scripts and styles.
Please make sure the "NextGEN Gallery" plugin is both installed and activated on your plugins page in the admin (it's a separate plugin available here). Once activated, the "Gallery" options tab should appear near the bottom of your left sidebar in the admin.
If you can't find the tab for your plugins page either, it's likely you're logged in as a user without administrative privileges. You can verify this by visiting http://www.yoursite.com/wp-admin/plugins.php.
Firstly, you'll need to deactivate Fancybox on the Optimizer settings page and click "Save Options". After that, simply navigate to Gallery --> Options --> Effects, select your effect and click "Save Changes".
Yes. However the small, already minified Fancybox script must be excluded from combining/minification or it won't function. This is true of any lightbox script.
For WP Minify, simply add /wp-content/plugins/nextgen-gallery-optimizer/fancybox/jquery.fancybox-1.3.4.pack.js in its js file exclusion options and clear the cache.
For W3 Total Cache, you'll need to select the "manual" minify option at Performance --> General Settings. After that, jump to Performance --> Minify where you can hand-pick the scripts and styles you want minified/combined (excluding Fancybox).
Any version since 1.6.2
It looks as though there may be a bug with one of NextGEN's settings. Go to Gallery --> Options --> Gallery Settings and make sure the first option "Deactivate gallery page link" is checked (as it is by default).
The drag-and-drop "Manage Albums" page in NextGEN does not auto-save like the WordPress widgets page. Click the "Update" button and your albums will display as they should.
Please go to GALLERY -> MANAGE GALLERY and select the gallery that's causing you trouble. Inside this gallery, ensure ALL image thumbnails are displaying and re-upload them if necessary. If they're missing, the "Path" field may have been changed, which will cause the slideshow to break.
Also, slideshows require two or more images in your galleries to function, else they'll break as above.
By default, Album pages don't include pagination...but you can activate this feature by adding a custom field called "ngg_paged_Galleries" on the edit screen for your album page in the WordPress admin. The value of the custom field should be the number of albums you wish to display per page.
After spending weeks working on integrating this, I've discovered it's not presently possible in WordPress to:
Conditionally load the required scripts in the header AND
ONLY load them if the widget is actually present on the page.
Since both the Fancybox and the NextGEN slideshow scripts must be loaded in the head section of the page so they don't break, and since the whole point of this plugin is to NOT load scripts on every page, I've had to abandon this idea for the time being. If you know of a solution, do let me know and I'll add it in the next version!
Apart from the [imagebrowser id=x] shortcode, I had hoped to add support for this on regular galleries and album galleries too, but unfortunately NextGEN's implementation to date is just too buggy, inconsistent and restrictive. For example...
I've tried to iron out some of these issues myself, but to no avail. Hopefully the team at Photocrati will look into this for a future release.
Before you can use JW Image Rotator, you'll need to download it here, upload it to your wp-content/uploads folder and enter the FULL filepath to its imagerotator.swf file at Gallery --> Options --> Slideshow --> "Path to the Imagerotator (URL)".
Click "Save Changes" when you're done and you'll be all up and running.
UPDATE: JW Image Rotator now comes bundled with NextGEN Gallery v1.9.9 and above, and requires no manual installation.
This issue is likely caused by the "Activate permalinks" option at Gallery --> Options --> General Options, which changes NextGEN's URL structure for things such as the "Show as slideshow" and "Show picture list" links, as well as navigation through your Album pages.
Optimizer Premium looks for NextGEN's default URL structure, which appends query string parameters to much of the navigation. With "Activate permalinks" switched on, these parameters are no longer present, which results in the plugin not recognizing where to add the necessary scripts for either Fancybox or slideshow functionality.
I'm currently working on a way to target these permalink URLs for a future version of the plugin, but for now, correcting the issue is as simple as navigating to Gallery --> Options --> General Options, switching off the "Activate permalinks" setting and clicking "Save Changes".
