Can somebody look at my problem?

[GrZeCh]

Hello!
I have little and I dont know where I should look for him. Take a look at this picture. I dont know why script is showing URL's without first letter.


When I go through this link browser is trying open this address:

http://address.of.my.gallery/ategories.php

So here too without first letter.

Can somebody help me?

Big thanks and one thing more.
