I'm sorry, but we cannot support old wpForo versions. The old versions may have some conflict with the current version of WordPress or other plugins. Please update the plugin to the latest version, delete all information in the error.log file and check again. 

The issue should be solved.

I'll ask developers about the issue and update this topic asap.

I'm getting a PHP Notice: Undefined index: attr in /XXXX/wp-content/plugins/wpforo/wpf-includes/class-members.php on line 1403

Some users can't post so I guess it could be related to this notice. ¿Any idea about this problem?
I'm using Wpforo version 1.5.5

Thanks in advance,
Germán
