please note the this page was linked incorrectly, the correct page is:

http://www.wallpaperama.com/forums/illegal-mix-of-collations-latin1-swedish-ci-implicit-and-utf8-general-ci-coercible-for-operation-t68.html

basically what this error means is that you have two types of encoding in your database, go to phpmyadmin and change to UTF8

thank you
