Disabled items still showing

I'm not using the 'forums' so I disabled them after installing the module (which is necessary to have some other modules).

The forum option is still showing in 'my account' at the left bottom as : _bx_forums: 0 _bx_forum_topics, 0 _bx_forum_posts

How can I remove the forum item from my account ?

You can delete that custom stat element from the database. Do the following.

Open phpMyAdmin.

Find the table sys_account_custom_stat_elements

Find and remove the entry that contains the label _bx_forums

Now for this to take affect either clean the cache or remove the file db_sys_account_custom_stat_elements.php from the cache folder.

And so I did :-) I also made a printscreen of the deleted element, so I can add it again when I change my mind afterwards.

But this should be mentioned as a bug and a ticket must be created.
