Fatal error: Call to a member function on a non-object in /home/myusername/public_html/components/com_comprofiler/plugin/user/plug_cbconnector/plugins/plug_phpbb3.php on line 883

The code on line 883 is:

[code:1]WHERE group_name = '"$db->sql_escape($group_name) . "'[/code:1]

Any advice on how to fix this is appreciated!

Not real sure have never seen this particular error before. Best suggestion is try the fix mentioned in this thread

forums.cbconnector.com/viewtopic.php?f=38&t=398

My server has register_globals off, so that fix does not apply to my situation.

Does your phpbb3 have any MODS which might mess with the DB object in phpbb3?
