I have a article directory http://isearchquest.com/articles, the problem is that a author cannot able to submit the articles. Whenever a non-admin login, it returns as " , this problem starts when i updated the article directory and roles plugin. Please help me out, what should i do to recover that.
Do you have a backup that you can revert the changes? Sounds like a bug in the plug-in system. Either that or try refreshing the user's access level by assigning the user to different role then back to its original role. May work in some cases.
