I couldn't figure out why this wouldn't work, particularly when I had not modified any files on certain sites I was trying to get this to work on. I was installing, hacking, installing and hacking. Throughout the entire process of redundancy, there was one thought that kept popping up in my head - it has to do with the template.

Well, I was right, but because each time I thought about the template as having to be the culprit, I kept referring to the front end template, and I could not figure how that would effect the back end template, knowing of course it couldn't in this case. Well, I had forgotten that over the last few weeks, I found a cool admin template that I had installed on several of the sites I'm working on, swapping out my personal template for a better-looking one.

Once I realized this, I switched my back to my template, which is a modified Joomla default template, and the next button worked again. The template that caused the issues was the Essential Plazza Black, which looks good and works for every other component but RSGallery2.

Hope this helps others.

I have been using RSGallery2 for over a year now and this one STILL GETS ME EVERY TIME.  Please remove the Next button from this screen, or make it work correctly, or put in BIG LETTERS at the top that the Upload button at the button is what must be pushed.  Very misleading and confusing!

Other than that, thanks for a great product!

I'm getting the same error.  This is at the initial batch upload page.  Is there a specific line of code that should be changed.  I'm using the khepri green administrator template.
