Post feed suddenly stopped working

Hi,

3 days ago (althoughI didn’t find out until just now) my post RSS Feed stopped working.

To my knowledge I haven’t amde any changes to the site, although obviously it possible/probable!

I also noticed that one feature I added manually stopped working at around the same time. I had to manually upload a new kses.php file again. Now I am 100 percent sure I didn’t chnage that.

When I try to view my feed:
https://www.planetphillip.com/feed/

I receieve this message:

XML Parsing Error: no element found
Location: https://www.planetphillip.com/feed/
Line Number 1, Column 1:

The comments feed:
https://www.planetphillip.com/comments/feed/
validates correctly.

This URL works but only gives the excerpt even when set to full content:
https://www.planetphillip.com/feed/rss/

I have tried replacing the rss.php file incase it somehow became corrupt, but this didn’t help.

I have removed the contnet of the last posts since the feed worked, in case something in there was causing a problem, same result: no change.

A Little more background.

I recently moved hosts and found the site slow and buggy. It would often not finish loading pages. I removed all plugins to see if that made a difference and it didn’t. It made me realize how many plugins I had and I have now reduced the amount I use, but this was over a week ago, so I don’t believe there is a connection there.

I also updated my robots.txt file to stop hotlinking, but I can’t see how that would change things.

Any suggestions or ideas would be greatly appreciated.

TIA
