I have setup 4 galleries with no issues at all. I have tried setting up a 5th gallery and I can upload the images fine, but when I try to view one that has been loaded I get a grey screen with the word 'LOADING' in the middle. Nothing happens.
Also the thumbs are not being generated. Not sure what the issue is... any thoughts?
