Weird problem...

My wordpress feed and yoast seo sitemap don't work. Line 2 issue, prob an unclosed tag, or extra line break. Not a coder, so I'm lost... Looked for <php and ?> and didn't see anything missing, or any extra spaces..

Before I had a plugin which fixed this by removing extra lines. But it no longer works.

The odd part..

The plugin never fixed my custom fields though. When in the admin area and adding a custom field, it doesn't auto refresh. Instead it doesn't do anything and adds it 2x. Updates to show this once I save it as a draft/publish.

*Also unrelated, backuppress gives me a 500 error, but then I run it again and can download my backup just fine. Everything's all funky..

...

What file should I be fixing?

I'm assuming it's the theme functions.php maybe?

Installed WP 3.6.x didn't fix anything... (Reason why the plugin broke and I'm back to step 1)

:(
