Style problems after changing permalink structure.

Thank you in advance for any help. I just donated since I've already gotten a ton of great information here.

My blog is at texasconsumerhelp.com. I'm running Atahualpa 3.7.3 and Wordpress 3.3.1.

Everything was running fine until I decided to change my permalink structure to custom. When I originally changed it to simply %postname%, I got a 404 error for one post ("Welcome") but not the other. I then changed it to archive/%postname% and at least the links work (no 404 errors).

However, whenever a permalink is clicked, the destination page does not render as it does on the front page. That is, the title font and menu bar font do not work like they do on the front page. Also, the permalink pages take longer to load, I imagine because there is something broken and the browser is moving on to other fonts, etc.

I am not an expert by any means, and, again, I appreciate the help from those who are.

Mike
