Gallery thumbnails not regenerated

    Due to problems with uploading new images to an existing gallery I flushed the thumbnail cache. Afterwards the thumbnails we not regenerated again.

    The images are embedded with URLs like this nextgen-image/67/180x135x100/crop/66a6dd3ae81764c85b8339d7bb6f685b on WordPress-pages … which end up in a 404.

    The gallery/<name>/dynamic and thumbnail folders are 777-writable … still nothing. Also trying to manually regenerate the thumbnails in the backend did not bring any change. The progressbar simply reaches 100%, I get a success-flash-message and not a single error message in the server log (even with WP_DEBUG enabled) – but no files are written.

    I also tried to flush the WP_Rewrite rules and downgraded from nextgen 2.1.26 to 2.1.23 … still without success.

    Do you have any ideas how to fix this or which parts to examine further?

    @rob1as – Are the thumbnails visible under Gallery > Manage Galleries? If this is the case you may need to clear the image cache under Gallery > Other Options > Miscellaneous. Also, it could be helpful to see this first-hand.

    Thanks!

    @photocrati – Yes, these thumbnails are visible and properly created when uploading new images to an existing gallery.

    But when trying to recreate a custom thumbnail size for a specific gallery it fails.

    Do you have any kind of logging in your plugin to narrow down the cause?

    @rob1as – You can the following in the appropriate place within your wp-config.php file:

    define('WP_DEBUG', true);
ini_set('error_reporting', E_ALL);
ini_set('display_errors', TRUE);

/** For NextGEN Gallery Testing */
define('NGG_DEBUG', WP_DEBUG);
define('SCRIPT_DEBUG', true);
define('CONCATENATE_SCRIPTS', false);

    The above may help but also to note, in most cases the above will also display notices that are not necessarily related to any particular problem.

    Thanks!
