Thank you very much! Searching through the diagnosing part didn't help but I at least was able to solve one of the two problems in my settings. Thereis only one problem left.
it tells me: This feed does not validate.
line 42, column 1: channel contains more than one image (2 occurrences) [help]
and in the source code it says for line 42 <image>
Do you have any idea how I can resolve that?
Thanks a lot already!
