Conflict with NextGen gallery

Correct. =) Boy, this just gets odder and odder that you can’t reproduce. =/

Still can’t reproduce it on Litespeed… What other plugins do you have active? Or can you reproduce the issue with ONLY EWWW and Nextgen activated?
Also, what theme are you using?

It’s really strange that the problem is even possible, because the section of code that uses the C_Gallery_Storage class checks ahead of time to see if the Mixin class exists. Both of those are NextGEN2 classes, and I don’t quite understand how one class can exist without the other class. I know NextGEN does some fancy stuff with their class loading, but this is baffling.

So the site in question is using the Photocrati theme, so maybe that’s it?

Once I have some time after a meeting, I’ll try creating a new site and see if I can reproduce that way.

That’s possible, I’ve never used their theme before. I have a copy of NextGEN Pro, but not their theme, so let me know what you find out.

Or you could just temporarily switch the site to twenty-sixteen or twenty-fifteen and see if the issue persists.

I could probably supply you with the theme should we need to.

But I’ll test with a fresh site and let you know. It is very odd that one class would exist, but the other would not. :/

Confirmed, it’s the Photocrati theme that’s throwing things for a loop.

I’ll contact you through your website to arrange getting you the theme to test with, if you like.

Also just tried with Photocrati Pro theme (5.0.1) and Nextgen Pro (which has to hove Nextgen Activated)… same result. =/

Fix provided worked great! Thanks!
