Hello Forum,New user of osTicket here, and just getting my legs under me. We have the application up and running and everything is operating well, however we have an issue when an image is added to the "Landing Page" but a user who has not logged into osTicket cannot see it. Looking in the browser dev tools, the call to get the image is throwing a "422 Unprocessable Entity" error on the service call.I've not been able to track down any other relevant log entries or errors, but could be looking in the wrong place.I am running on Windows Server 2012, with IIS 8, and PHP 5.6.3 with MariaDB 10.1.I saw another issue in the forum similar to this which recommended upgrading PHP to 5.6, but since I'm already at this level I was curious if others had run into this.Any assistance is much appreciated.
