Error message only in Private Forums

[OakleyForum]

After all that happened yesterday with my forum crashing(read more here: http://xenforo.com/community/threads/forum-crashed.48688/), now when you try to access one of the private forums on my board, I get this:

An exception occurred: Declaration of XenPlus_Dom_Document::loadHTML() should be compatible with DOMDocument::loadHTML($source, $options = NULL) in /home/oakleyfo/public_html/library/XenPlus/Dom/Document.php on line 26

It looks to be an issue with the XenTrader add-on.

 

[OakleyForum]

Yeh you're right. Disabled it and I could access the area. I will try re-installing.

 

[OakleyForum]

I completely uninstalled and re-installed it and I'm still getting that message.

You will need to post in the add-on discussion thread for support with the add-on.
