I am having a problem I can not readily fix or identify. Your help is greatly appreciated.

I installed the v3.6.6B on my website biaf.com. After I configure its every step to the letter and enable it in the admin with aliases, I can go to the home page and a second click on a category but after that either the next category or product page takes for ever to load. When it does finally load it is without formatting like it lost all of its css.

I have reinstalled it twice and even tried install the v3.6.7B but to no luck. Funny thing, after i installed the new version and went to module manager, it didn't update to the new sql and version number.

I currently have the same version running on my other website just fine on the same server. I know I have all the capabilities to run it just fine.

Side note, this is my 4th time installing without mishaps on other sites. I am familiar with the module.

What should I check?
