Problem Solved!
removed feed-rss2.php from wp-content/theme/mytheme
installed wordpress on local host. took file feed-rss2.php from wp-includes and moved it to the same file location on my server thus overwriting my theme creator’s file.
Works like a charm now.
This is at top of validation. Where can I find this code? It looks as if there is a space that should not be there.
This feed does not validate.

I found the tutorial. I get to the screen after selecting manage and the migrate button does not activate any change.
