Feed does not validate

Hey all,

I’m trying to submit my RSS feed to several sites, but according to: https://feedvalidator.org/check.cgi?url=http%3A%2F%2Fwww.tonymoore.nl%2Ffeed it’s not a valid feed because of ‘line 267’. I’ve looked in the source and original post, but I can’t find that specific line.

Any ideas?

Thanks in advance!

Grtz,
Tony
