I've got a very bizarre problem. When ever I go to edit an article and include the phrase "electronic cigarettes" in either the title or the body, and click save, I get the following error:
Access is forbidden to the requested page:
/node/9/edit?destination=admin/content (port 80)"
This is on a blue background.
I've uploaded a plain HTML page with the phrase "electronic cigarette" and successfully viewed it on the same server, so it seems it's not a server side ban.
If I don't include the phrase "electronic cigarettes", everything is fine. Also "electronic cigarettes" is also ok. It seems like there's a bizarre word ban on "electronic cigarette".
Does anyone have any idea why this would be the case? I've removed all non-core modules. Also, is there something that assists debugging such an issue (ideally, some sort of step-by-step log of the tests/actions Drupal takes to end up at the error page). I don't recall setting up a word ban list, and I'm worried there's a whole lot of other words that are banned that I don't know about.
