Hi

It may not be a theme option, but from th the dashboard I changed my permalinks custom setting from year, cat,post and selected postname and inserted a code into the htaccess file however the website shows in Fire fox and not in IE now. Using all the lastest versions.

I knew I should have kept it as it was !

Any helep would be most appreciated.

What version of Atahualpa nd WP?
What is the URL?
What code did you put in the htaccess?
do you have any caching plugins? Did you flush the caches?
