Thank you for your fast reply.
The thing is, i didn't add the template, a hack did.
Look, i'll explain it to you.

My "project" was to merge Who has visited & Track guests. So i took some lines from track guests template and added to Who has visited template. Result ? One fine column with members visits, guests & spiders on the same line.
Doing this, i don't need the track guests template anymore.
You know what i did ? i just empty the template until i find a way to delete it. dumb.
