I’m seeing similar errors on at least 2 different discourse installations. Does anyone have any idea what the following is about? The most serious manifestation is when trying to post from the web interface, which fails with a 500 error. the rails/production.log has the following: Started POST …

Some more info. The problem started when the last discourse update was put through from within the discourse web interface launcher rebuild doesn’t fix it. It seems it matters who the posting user is. Provisionally, it might be that higher trust level users are affected and low trust level not so…

getting the same error on posting replies…not all users or all replies : Completed 500 Internal Server Error in 134ms (ActiveRecord: 4.3ms) NoMethodError (undefined method staff?' for nil:NilClass) /var/www/discourse/lib/validators/post_validator.rb:94:in unique_post_validator’

Validation error: unique_post_validator() doesn't know who the acting user is

I believe this bug was already fixed today, so pull latest and rebuild?
