New Site Problems - Populated Sub Category doesn't display?

Hi,

I'm in the process of setting up a site with Zen Cart and have run into a strange problem, I wonder if anyone could shed some light on it please?

I have created my menus which all display perfectly, until I put a product in them, as soon as I do that I can't open the sub category I put it in, yet the product itself is accessible via the new products link...any ideas will be much appreciated!

A link to your site would help.

Apologies,

I've just run the debug tool and got the following output:

[22-Sep-2009 21:46:41] PHP Warning: Cannot modify header information - headers already sent by (output started at /public_html/includes/languages/english.php:1401) in /public_html/includes/init_includes/init_templates.php on line 78

Apologies for wasted post!

Problem solved, I had 2 extra lines at the end of english.php removed and now working.
