ok you doing the equivalent of sending me an image of your car engine and expecting me to tell you what the noise it is making is caused by. 🙂 🙂

I would suspect it is theme related, and menus and scroll are theme related.

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
