I don't know what might be causing this. I am completely dumbfounded.
I am trying to create a 'draft' post. Subject is 'test.' If the body of the post contains a certain string, then an attempt to save it gives me a 403 forbidden error. If I avoid that string, it will work fine.
The text of my original post was much longer, but through extensive trial and error I was able to reduce it down to:
will give me a 403 forbidden error, while
does not. This simple addition of a comma solved the problem.
Can somebody else test this? This has got to be one of the strangest errors I have ever seen.
