PROBLEM html showing

I dont know why but on my message board page and at the bottom of my forum im seeing coding,

what can i do to correct this, what steps should be take..

heres a screen shot of what happens... and one of the group section

This problem has mostly to do with that your php is not compiled with XSLT. 
Please look at your servers php settings if XSLT is enabled.

If this is enabled, then a other can be that there is a servers php file that is not have a correct permission. 
For this you have to contact your server hoster.
