First of all i would like to say hello to all in here Tho, if i missed a topic, please move it onto the right place.

Well, i got to make some changes on the web site which has been make with zend framework. So i am kinda noob on ZF But job must have be done.

So i started to read tutorials and so on.. My task was to add some functionality on the existing web site.
I did it on my localhost, and everything is just fine. But, when i upload files to the web server, it wont work.
What could be possibly reason? Or reasons? Any ideas? Where to look into?
Thanks a lot in advance,
Vladimir
