I did a validate of the .rss newsfeed just as a golly gee whiz and found that there is a problem on line 4 of the feed. I believe it is a simple fix in just removing a return putting line 4 onto the end of line 3.
Line 1348 of lib-common.php (1.3.8) remove the slash /n (the slash actually goes the other way but it won\'t disply on here) from the middle of the line. The line looks something like this.
fputs( $file, \" /n \"http://my.netscape.com/publish/formats/rss-0.91.dtd\" >n\" );
However I noticed that this isn\'t necessarily what should go here. According to what I\'ve read you don\'t even need that line it\'s optional. That was an old 1999 Netscape standard which has since been updated but even then it was optional and didn\'t necessarily point to Netscape.
