Alright, im gonna be honest, I'm actually using osCommerce, but i no that zencart is derived from osCommerce. The reason why i no this is cause i set up my OWN site with zen-cart (and im loving it by the way) while my client, (who prefers osCommerce) is having trouble with his site.

The problem he's having (which i'm hoping someone from here might be able to help me out) is that when i access the admin section of the website everything works properly...when i click 'categories/products' it goes to the page but the page is completely blank. The only thing that actually shows is the title of the page sayin "categories/products"...and thats it.

Any suggestions? really appreciate it.
