Environment:
CB 1.3.1
Joomla 1.5.22
PHP 5.2.15
Joomphpbb3 bridge from JoomPlace: 1.0.0
Failing Module: comprofiler.php at line 1915 which reads:
$_PLUGINS->trigger( 'onStartSaveUserRegistration', array() );
If the bridge plugin is removed problem goes away. Uninstalled both CB 1.3.1 and JoomPHPBB3 bridge. Reinstalled and configured CB 1.3.1 - added user OK. Installed and configured JoomPHPBB3 bridge again and failed at same place.
Site is on a development VPS host (soon to go live) so I have some flexibility with setup and testing.
Thanks,
