I am using as below :
osTicket Version v1.15 (d5ee0df)
Web Server Software Apache
MySQL Version 5.7.35
PHP Version 7.2.34
Although we had wait until the ticket is appeared the "all changes saved" message. Then pressed the post reply button.
It will happen that the attachment is missing sometimes(10%) and no error message to check.
Please advise that how to debug this error.
