Merged Warning: array_intersect(): Argument #2 is not an array in ../plugins/kunena/joomla/access.php

Okay, forget my first post, I managed to work it out for myself. However......

I have just migrated a 1.5 Joomla! website to 2.5 and have successfully migrated the forum. Everything seems to be going okay apart from to errors that are showing an the forum, and in the backend. I really don't know where they are coming from, maybe it's got something to do with a missing plug-in, I really don't know. Maybe somebody else on here could tell me what is wrong. I have included a screenshot showing you exactly what I am talking about.

Okay, I have isolated the problem down to the "kunena Joomla! integration plug-in" if I disable it then the errors go away, however there is no login panel on the forum so obviously I need this.

Do those warning message go away when you turn off error reporting in Joomla?

Hello,

What exact Kunena and Joomla! version are-you using ?

Hi guys, I'm not sure about Joomla! error reporting, where do I find this?

I'm using Joomla! 2.5.6 and kunena 2.0.4

can okay, I found the Joomla! error reporting in global configuration. I changed it from system default to none and the errors went away. However, this doesn't solve the problem as the errors shouldn't have been there in the first place. I'm wondering if I made a mistake when I moved the database overand renamed it
