Bug report: Missing security token
 

I've recently started getting occasional "missing security token" error messages when sending private messages. There doesn't seem to be any pattern to them, but they might be associated with cloudflare?

They don't happen every time, but sometimes when I hit send on a PM, the site runs a cloudflare security check which appears to pass but then takes me to an error message that the action could not be completed due to a missing security token.

So far, hitting the back button and resubmitting the message appears to fix the issue.
