Category as subdomain

Some of your resources are not loading properly, even on your main domain.

Using Google Chrome, load your main page, open the Elements Panel by hitting the F12 key. In the panel that opens, look in the upper right corner. There will be a red X with a number next to it. That shows you how many errors you have. Click on the X and it will open a pane that will tell you the nature of the errors.

If you do the same thing on the subdomain, you will notice you have more errors. If you resolve the errors on your main domain, you will probably find the reason for the other errors.
