I had faced an issue with RT v4.4.4 that when I write an IP within the message body. the message doesn’t appear and tell me that there is An internal RT error has occurred.
This is happen when I create and new ticket or reply on a ticket.
if I reply on a ticket with a message like this
" your firewall public IP is 22.214.171.124 "
the error will occur as below screenshot
but if I remove the IP number from message no error occur.
Any help to solve this issue
