Friends are giving this error for me!
AH01071: Got error 'PHP message: PHP Fatal error: Call to undefined method stdClass::select() in vanilla/htdocs/applications/dashboard/models/class.rolemodel.php on line 195\n'
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
_Sorry, I could not edit the topic.__
This error is in vanilla, not in plugin!
This a messager error in my apache log!
Resolved, was a setting in config.php.
I returned to the standard and is working!
