RSS Feed won't work – tried evrything!

My RSS feed will not work on my Website and I’ve tried everything! https://www.wrestling-edge.com/feed –

I’ve gone to Facebook (as it uses the feed URL) to see what the last post published was (5th November) and gone from there to see if there is any html in posts/comments messing things up… no luck though!

I think the problem line from source code is: <div id=”open” style=”display:none”> but I don’t know where that is – it’s not in posts or comments.

I’ve tried disabling plugins and enabling them one-by-one to see if it solves and it didn’t.

My feed to twitter is still working oddly. Any help would be hugely appreciated!
