First, let me apologize if this is a redundant thread. I've looked through a dozen other threads, but none mimic my issue or have any suggested solution.
When I upload an image and have it generate a thumbnail, the 'Create new thumbnails' window pops up with the status bar denoting how far along the thumbnail generation is. Then the status bar disappears and the windows just sits there with the 'Create new thumbnails' message. Nothing else happens - no errors occur. I have to manually exit the window.
Now I'm looking at my gallery and there are no thumbnails next to the items. The thumbnail column is simply empty. I can click on the individual item and click 'Edit thumb' and the proper image shows up with the cropping tool. I crop and click 'Update' and it says 'Thumbnail updated'. I then exit that window and there's still no thumbnail in the thumbnail column. The actual thumbnails do no show on the webpage either; however, the slider works perfectly.
I've tried changing all of the settings for the thumbnails in the options. I have nextGEN Gallery fully up-to-date (1.7.3 as of 1/24/11). I've tested on Chrome, Firefox 3.6 & 4, IE8 & 9, and haven't had any luck with the thumbnails working. It is important to note that the very first time I installed nextGEN Gallery that the thumbnails did work. I ended up deleted the aforementioned gallery and haven't had luck getting thumbnails to work since. I've reinstalled the plugin as well. I'm using the Green Stimulus theme... maybe there are compatibility issues?
I eagerly await your opinion on this issue. Thank you.
