I run the latest versions of both joomla and the rss reader.
But when i try to add a second feed i it only reads the latest one in the list, so i was wondering if i need to separate the feeds somehow?
If i try adding a blank line get this message in the frontend feed:
Warning: fopen() [function.fopen]: Filename cannot be empty in ../libraries/joomla/filesystem/file.php on line 322.

Please advice

Hi. You need to separate them with a new line ( hitting the enter button ). Ensure that the URLs you provide are correct.

Both rss feeds works fine, but they still dont show up in the feed.

Iv been separating them by hitting enter but no...

Please i need help with it.

Can you please post the URLs of the feeds? Also ensure that you are using the latest version of Simple RSS Feed Reader.

yeah, im on the latest versions :)

Ok i found the issue. Your RSS are invalid. They do not include a proper date field. They use their own namespace and that's why the plugin cannot parse them.

but they work if I use one and one?? Thats strange?

No it will not work correctly. In order to work as expected you need to use valid RSS feeds.
