HTTP 500 error on WP site [solved]

I’m new to EE, I setup the site last month and it was running fine.

Yesterday I installed phpmyadmin and that runs fine too on 22222

But suddenly my website can’t be accessed, the /wp-admin/ can’t be accessed too.

I have one directory in that domain for other stuff and that works fine.

I’m using Cloudflare, and their SSL in case that makes a difference.

How can I find the error?

Update: found it. It was a really stupid error. I had a bunch of files open in notepad++, including wp-config.php , by accident I paste something there, and by another great stupidity it got auto-uploaded by FileZilla.
