Pulling my hair out on this one – Forums and Topics work just fine in the admin and in the front-end. However, Replies totally crash the site – on the front-end, they just fail quietly, but Add New on the Replies page in admin causes WordPress to fail. Trying to track down what could possibly cause this, because it feels really strange!

Copying over the first 100 lines or so of the stack trace to see if ANYONE has any idea what could be causing this.

Error:
Xdebug has detected a possible infinite loop, and aborted your script with a stack depth of '1024' frames

I can only suggest the basic fault finding

viz :

it could be a theme or plugin issue

Themes

As a test switch to a default theme such as twentytwenty, and see if this fixes.

Plugins

If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

If you cannot do this to your site (say because it is live) then use the ‘troubleshooting’ features of this plugin to let you test without affecting other users

Health Check & Troubleshooting

Then come back

[maldiv097]

on the front-end, they just fail quietly, but Add New on the Replies page in admin causes WordPress to fail. Trying to track down what could possibly cause this, because it feels really strange!

Never got this working and didn’t have time to fully troubleshoot – since our needs were pretty simple, we moved back to use a custom post type and built-in WordPress comments for our “forum”
