Internal Server Error only when saving CSS

Hey everybody,

I’m having a strange problem with my site.
Whenever I hit save stylesheet I get a 500 Internal Server Error, it still saves my Stylesheet so its not causing me much grief but I would like it if I didnt have to deal with this every time haha

The problem started randomly and was working for about a day and a half since I last added a plugin. So I don’t think that would be causing it.
Ive also tried adding a “php.ini” file but that causes my site to be unreachable for some reason.

Any insight would be appreciated
