Hello, OSTicket Information:

We discovered that we are no longer able to add collaborators to tickets. When trying to add collaborators to tickets; we type in the name of the person and nothing appears in the box. I have confirmed that these users exists in the directory (Agent Panel -> Users -> User Directory). I have looked into the logs on the server; there is nothing in the MySQL logs, PHP, or Apache2 logs. Any suggestions on how I can troubleshoot this issue?
Thanks for all your help on this!
