I have just switched over to an SSL so my entire site switched from http: to https: . My RSS Feed will no longer validate testing at the W3C validator. I am using K2 and JoomSEF. I switched on SSL in Joomla Config and JoomSEF and have tried one or the other off, but always the same problem.

Hello,

K2 uses Joomla!'s default feed functionality.
Is it possible to have the link's feed?

Thank you for replying. I was able to determine there was an incomplete chain with the SSL that was causing the problem. Nothing to do with Joomla at all.

Nice to hear that you sorted it out.
