"Suggest Listing" and "Suggest Category" do not work on Omega

[subet]

Hi,
i have installed eSyndicat 1.6 Omega to my Win2K3 server. I am facing some problems.

1. In the code, DIRECTORY_SEPARATOR was giving errors because of win2K3 server. I replaced them with '/'. The problem has been fixed.

2. I am trying to add a listing at user interface. When i submit the form, sometimes it hangs, and mostly it gives error "An error occurred during http request. Please try again later."

3. I am trying to add a listing at the admin interface. When i submit the form, an empty page comes.

There is also same problem on "Suggest Category" page. Same error.

I thought that it can not add any records to the database, but registering a new account works.

All other things looks ok. The URL is : www.zoroyun.net
