Images Per Page must be greater than 0.

“Images Per Page must be greater than 0.” is the error I get when attempting to do anything with a pre-existing gallery (saving, adding image, removing image, etc).

I had hoped the issue would fix with the new update but it didn’t. The issue started after the last update. I can create new galleries and they work fine. I just cannot work at all with the pre-existing ones. I’d like to not have to recreate all my galleries ??

Any suggestions?
