I've had my 1.5.2 installation up and running for two days now. Tonight the RSS 2.0 feed stopped working.
"Reference to undefined entity 'raquo'. Error processing resource 'http://www.load.se/feed/'. Line 10, Position 15"
Apparently it is getting upset by html special characters. They have been there all along and it has not been a problem earlier. I have played around and it gets angry by other special characters as well.
I haven't done anything to the character encoding (im sticking to UTF-8 and hopes that my swedish writing will survive it :) ).
It also seems that the rss-feed is cached somewhere. If i try removing some of the special chars i still get the same message - with the original document/database entry obviously changed.
