I cant comment or vote PBE community topics or open a ticket on "Report A Bug"

I can not comment or vote on topics from the PBE community, I can post topics normally, but when I try to comment or respond it does not work, as if the "post" button is off, when I try on a topic, a message "So sad ... you are not authorized. ", so I do not know how to solve this When I have open a ticket it appears an error "We encountered an error while trying to process your bug report. Please try again in a moment" this occurs infinitely regardless of the schedule
