Font display and hyperlinks in iWeb

I have published my iWeb site with an ftp client. I have the same font throughout the website.

http://bricksandcartwheels.org

The correct font only appears on some pages- ie the 'about' page appears perfectly.

I have also changed the .css files to remove the underline and change the hover colour to orange, but again this only works on some pages. I thought have been something incorrect in one of the .css files but on the 'photos' page half appear correct and half incorrect.

Would any one be able to help with what I may have done wrong?

Thankyou!
