I am working toward upgrading to IPS5 so maybe this does not matter but....

When I enabled and configured Meta Pixel in my IPS4 site I was no longer able to edit forum posts. I could click edit and work in the editor but the save button was dead.

As soon as I disabled Meta Pixel the issue was resolved. Weird conflict?

I will need Meta Pixel when after I upgrade. Is this a know issue?

Unfortunately, on my test version 4 instance, I am not able to reproduce this. I would suggest disabling any third party applications/plugins/themes/javascript/etc... to see if that is causing the conflict.

I was really just asking if this is a known issue. I'm going to cross my fingers that after I migrate to version 5. I won't have to deal with it.

It is not a known issue :)
