osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now
[resolved] Unable to answer to tickets "This action requires a lock. Please try again! "
I use OsTicket v1.10 with PHP 7.0 for a week, it worked well first days, but I can't answer anymore to tickets. When I try to answer, closing or not the ticket, I get "This action requires a lock. Please try again! ". I'm still able to change ticket status to closed or resolved normally. "Lock Semantics" is disabled in admin parameters.
