I had a similar issue.
But the origin of the trouble seems to be the Nginx cache.
i know this is a vague question, and one that's probably solved by me re-importing my forum; however, I was wondering if there is a good way for me to claim ownership of the "Guest" posts from nodebb (or changing the database in redis!).
I recently imported my forum from Discourse and everything works great, and my users have already started using nodebb--i'd hate to have to flush it and re-import it again just so I can re-claim ownership of my posts. None of the other posts have problems, I'm guessing because of my existing admin account.
I'm willing to mess around with redis and write a script or small java application with jedis (the latter would be easier for me) to circumvent a reset of my forum. However, I am a complete noob with redis
Can someone lead me on the right track?
