One of the Drupal sites I run has recently acquired a strange problem, I believe through some malicious intent, where when my users preview or submit any content which contains HTML markup, they fail to to post, instead returning the user straight to the root of the site without anything being stored.

I've checked the watchdog logs and after one of these failed posts, nothing appears in the log.

I mention that I think this is malicious because although now I'm up to date and running 4.7.6, I believe I have had a problem similiar to this before and a maintenance releases/system update fixed it previously leading me to think it had been a security vulnerability.

My current work-around is to disable all but the Line break converter input filters and the preview and submit buttons both function correctly after that, however I would like to enable posting of HTML again soon.
