Can’t Add Content to New Pages

Hi i have a particularly irritating problem.

I’m trying to add an About Me page to my site. I can add the page itself but once i put any sort of content into the page once i click save or publish it will refer me back to my host.

Now i don’t know if this is a problem with the host or with word press.

any help would be much appreciated
