Hi, thx for taking the time to aswer.
I´m runing osticket V1.10.1
apache 2.4.35
php 7.2.10
MySQL 5.7.23
Everything runing via wamp on a Windows 7 Enterprise service pack 1 (I have no control on the SO, so it can not be changed)
by "stop working" I mean what I tried to explain later, in those tickets I suddenly can not post any more replies, as it can be seen in the img, the ticket abruptly ends and the option for posting a new reply just does not exist anymore.
Cheers.
