Roundcube request check failed

Getting an error when trying to login to a roundcube mailbox.
is there a quick way to clear this, think i remember clearing cache some where but cannot remember as not seen this in a while.


That is not an error I’ve ever seen, before. Please submit a ticket.


sorry for late reply.
This error was shown for just one user, not sure it was the correct way but cleared the Roundcube session and all working as normal again.
