I am trying to edit my nomination on the Super User Election, but every time I submit, I get a
Suspicious Request, as below:
Sorry, your request could not be completed because it looked suspicious. If you meant to perform an action on Super User, please return to the previous page and try again.
I tried clearing my browser cache, flushing my caching proxy on our network (after hours, don't worry!), and even rebooting my system, but it does not go away! I can still vote up or down, or edit questions on the main site. This has been happening since around 2300 hrs UTC, yesterday.
