I am not able to upload images.
I am using v1.8.4 of NextGEN Gallery.
This has worked previously for many galleries but has now stopped.
After I create a gallery name, then select "upload images", I then select multiple images for upload, it then starts to upload the images but pauses after the first one. No errors on screen, it does not quit, the "upload images" progress bar changes from orange (100%) to grey (0%) as it starts the next image. It stays on screen as if it's still doing something, but it will not go any further.
Does anyone know what's causing this? Any logs I should be looking in? This is on a self-hosted site so access will not be a problem.
