   I am unable to generate thumbnails using NGG 1.9.1 on WP 3.3.1. I have tried from the flash uploader, from the regular (non-flash) uploader, and by selecting 'Generate Thumbnails' from the drop down on the Manage Gallery page. The thumbnail directories are being created but files are not being generated/added to the folders.

   The only way I can create the thumbnails is by entering each individual gallery, selecting 'Edit thumb' for each image individually, highlighting the entire image, and updating. Considering I have hundreds of images to upload, this is definitely not a viable option.

   I have deleted NGG, deactivated all other plugins, and then re-installed NGG. It didn't work.

   I have tried NGG 1.8.4. It didn't work.

   I always receive the following message(s), with each attempt returning a different ID number.
   ID 6: A failure occurred
   ID undefined: A failure occurred

   The Plugin Check Utility has passed all three tests.

   Any help/suggestions/shots in the dark would help at this point!

   Hi J_nichol,

   If the images are real big in kb's, I remember that can have an affect on processing. I had to adjust my memory limit (your is at: PHP Memory Limit : 64 MBs);
   To increase the memory limit, I opened up the .htaccess file in the root WP directory, and added this to the very top:

   php_value memory_limit 120M

   which may be a too large amount, but it was adequate to get thumbnails created in my case.

   Thanks for the suggestion @Rain Wilber!

   I use GoDaddy for hosting so I had to make the change by adding "memory_limit = 120M" to my php5.ini file. The increased memory limit is reflected in my server settings on the NGG Overview page. Unfortunatley, that did not fix my problem. I am still unable to auto-generate thumbnails.

   I might also mention I have NGG running beautifully on 3 other sites all using GoDaddy servers. This is the only one using WP 3.3.1 AND the only one with the problem. It works fine on WP 3.3.0 without increasing the memory limit and using the exact same images.

   Does anyone know why the latest WP update would have broken NGG?

   I have a similar problem. The thumbnails disappeared before I updated the site to WP 3.3.1.1

   However when new images were uploaded, the new thumbnails appeared but the old ones or existing thumbnails did not.

   I have upgraded to latest WP, the latest images that were put up are ok and show as thumbnails, but the previous images do not appear as thumbnails

   Need some help on how to fix this, I have had the memory increased to 256 m but this has not helped.

   My server tech added the following to php.ini

   memory_limit = 64M

   and that has fixed it.

   Good Luck x

   @j_nichol - I have encountered the exact same issue on sites running WP 3.1.1 and NextGen Gallery 1.9.1 and 1.8.4 on Godaddy. I have increased memory limits in the php5.ini file as well to no avail.....not sure what else to try. Have you had any luck?

   I re-installed 1.90 over 1.92 and solve my problems, it's way more reliable. I also did the php5.ini increased memory ages ago.
