I have a moeRSSe (huge) problem

I seem to have landed in RSS hell…..a while back everything was fine and my rankings were climbing on Amatomu. Around the time that WordPress upgraded their software platform my RSS Feedburner feed (and the normal one btw) stopped validating - the feed still delivers posts but does not validate. This means that my rankings on Amatomu are dropping….fast! It’s sad…my readership and stats are increasing by the day yet my listing is taking a real dive.

Both Henre and Alan offered advice via IM - the bottom line is that I don’t know what to do and I’m about to rip all my hair out and that would be a real shame because somedays that’s all I have going for me I’ve removed as many extras as possible but as I’m on a WordPress hosted blog I don’t have any weird extras or plugins (because it’s not allowed - this is another debate.)

This is the error message
- after trawling tech forums I know that I’m not the only one suffering from this error.

I’m no techie but it seems that I’m missing a / (forward slash) after a line of code that ends in mrss.

I can’t edit my CSS though so am I stuck and doomed to be listed as the 3587th blog in the SA universe? *sniff* that would hurt…..suggestions / help / advice anyone???
