My website shows up just fine in Firefox, however, all layout, fonts, and coloring seem to be ignored by both Internext Explorer 6 and Internet Explorer 8. Is there some sort of over-ride I can try?

This site has been online for about 2 years now. I haven't noticed this kind of problem before with IE except for once it occured for maybe a few hours, but then resolved itself.

I added the recommended security patches about 1 month ago... would they have caused some change? or would this be an issue I need to address with my webhost?

Thanks for your help in advance.

My web host cannot add the "Limit" keyword to the AllowOverrides parameter of your domain's vhost configuration in their server's httpd.conf settings file.

I tried changing the name of the /includes/.htaccess file to ".httaccess_OFF" but that made no difference. The layout of my admin area have not been affected.

Any other ideas?

Hello again. I fixed the problem by comparing various template files with the original version of zen-cart and found that there was a missing "/>" (without the quotes) in the includes/templates/templates_default/common/html_header.php file. I added those 2 characters back to the file and the Internet explorer problem was fixed.

Couldn't say how those characters went missing, but I thought I'd pass on the answer in case someone else runs into this sort of problem.
