Feeds should not be served with the "text/html" media type [help]

Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Ten theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

My Rss Feeds have been working fine. until now I installed one new addong a security add on and haved deleated that as well.

I also made some cahnges to w3 cashe and have deleated that addon as well.

Whats funny is before i deleated the w3 cashe thre was alot of data in the valdation area but still blank fist line

I realy think W3 cache messed something up. I have gone though the steps of removing it totaly with documention online with additional files to remove.

However the validation section is blank which i find funny since there are alot of post and its set to show 10 past i WP settings

Please help i am stuck at the moment

Did you try any of the suggestions I gave above?
