MyBB Hacks

Some members of my forum have found this error

Any idea of what could be causing it?

Fatal error: Call to undefined function xthreads_rm_attach_query() in /home/beatdjn/public_html/foros/inc/xthreads/xt_updatehooks.php on line 492

I happened to notice this myself.
Fixed in v1.52.

Thanks for pointing out!

Glad we helped out in some way =)
