Malfunctioning RSS-feed plus bizarre chars in top of some pages

Hey, all!

I have recently moved my WP 2.0.2 blog ( https://niklasblog.com) from one host to another. As I restored the MySQL-database and made sure the files were in place, however, a couple of quite bizarre errors showed up:

1. My feeds ( https://niklasblog.com/?feed=rss2 ) don’t parse like they should, ending up with these weird top four rows in the top of the feeds:

p');

endif;

…and I think this is consistent with my second problem:

2. When someone clicks one of the FAlbum-pictures on my blog, the picture shows nicely except the code p'); endif; ?> at the top, e.g. on this page: https://niklasblog.com/wp-content/plugins/falbum/wp/album.php?show=recent&photo=128989089

Any help on this would be GREATLY appreciated.

Sincerely, with many thanks for any kind of help with this,

Niklas
