Help with templates

[GuaRRand]

Hi,

I dunno if this is a good place to ask for help, but this is the most active forum if seen so far.
So i hope one of you can help me.

I've got site (duh), www.glcoti.com and i've had a problem with installing an addon.
It resulted in an error in the index.php and it wouldnt load my site.

After restoring the backup from a day before, the site worked again....but without some of the addons i had installed weeks/months before.

For instance the VBshout, Shoutcast_lite and topXstats have just disappeared from my forumhome.

I checked if the addons we're still active and installed corerctly and nothing changed.
The direct links to the pages still work (so http://www.glcoti.com/topXstats.php still works and so does vbshout...) but the template which should show on the forumhome doesnt.

I checked if the specific templates were still correct, and also there i saw no difference/problem.

I then deinstalled and reinstalled the addons in question....and STILL nothing.

Could someone please help me out here?!?
I've run out of ideas and i get all cranky when stuff like this happens and i cant explain whats wrong.
