[3.8.6] Problems after upgrading

[SebKom]

I just upgraded from 3.8.4 to 3.8.6 a few minutes ago and while everything the first page of the forum is ok it doesn't display the threads or any private messages (although they can be sent and received).. Sections and sub-sections are fine though.

Any ideas on what it could be?

Try creating a new default style, see if that produces the blank pages?

If that does not help see here:

Disabled the plugins and works fine, now only got to fix the plugin code. Thanks! :)
