I talked to my hosting company today about this, they said it wasn’t them (I thought something might have happened while they were updating my mod_sec, but no).
Anyways, if someone is kind enough to take a look at this for me, I made a page of screenshots (in progressive order) of what happens when the issue occurs. Cannot believe I’ve spent four days on this! I’m sure I’m just having a newb moment…?

Also, it doesn’t work in any browser.
Hey – I guess no one else was having this issue but just in case, it turned out to be a security_mod issue that I was having with HostGator. I live chatted with them and it was totally fixed. Ask them to look at your security settings in the php.ini file. 🙂
