We use the JIRA Service Desk for allowing our clients to enter in support tickets for our software product. Recently, a bunch of clients are stating they cannot enter in tickets because of two reasons: 1) the page is cut off and does not show all necessary fields that should be there.....

.... so when the client tries to proceed, they run into the second issue 2) an error message popping up on their screen stating to contact the Site Owner.

We have tried everything from restarting the computer. uninstalling and reinstalling Google Chrome, updating their OS (if updates available), all to no avail.
Has anyone else experience this issue? Or can lead me in a direction as to why this may be happening? Possibly a plug-in issue?
Any thoughts would be greatly appreciated!
Thank you!
