Hi there,

Can you disable all plugins except GP Premium to eliminate any conflicts first?

If that doesn’t help, anything added in GP hooks or any custom functions?

Let me know 🙂

Hi Leo, I only have this appear on one date and it is a live site so I can’t just turn everything off and wait. I was hoping you had seen it before…

We have hooks, yes.

Unfortunately we have not had other reports on this and both GP Premium and GeneratePress theme haven’t been updated for awhile.

I assume it’s something specific to your install, a custom function you’ve added or another plugin.

The best thing to do here is to duplicate the problem on a staging server so we can do some debugging.

Let me know 🙂
