Products not displaying after clicking on category

I am using the latest Zen Cart version...I have two categories added to my site and products underneath each, however if I click any of the categories it just refreshs the main page and still displays the main page and doesnt display the products under the category..

Can someone tell me how to fix this? It is very frustrating and I can not find anything in these forums or on google..

Switch to the classic template and see if the issue remains
If not it is an issue with your template

Looking at the breadcrumbs on this page says to me there are no categories at all

Like Kobra said, swith to the Classic template and test again.

Yea I did try that, the issue still remains, so it isnt the template....

Any ideas?

Go to phpMyAdmin and browse the:
products

table of your database ...

Do all Products have a master_categories_id set?

Browse the:
products_to_categories

of your database ... are all of products listed in that table with a valid categories_id set?

Yep it has everything in the database just fine....Hmmm any other ideas?

I would next try the Debug Tool from the Free Software Add Ons to see if there is any error or errors being thrown when navigating the categories ...

Otherwise, get something like Beyond Compare and start comparing to a clean Zen Cart v138 ...
