My theme uses the bbpress plug-in. When I activate this plug-in, I can’t delete users in “user menu” of admin bar. When I close this plug-in, I can delete users normally. why? Is this a setup problem？
In addition, I often receive some “machine users”. I don’t know if this has anything to do with bbpress?

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
