I've been using osTicket for almost a month with no issues. However this morning when accessing either the staff or client, the custom logo displays a broken image symbol. I rebooted the server and cleared the browser cache. I went to the admin panel to the logos screen and it too has a broken image symbol instead of the custom logo. I deleted the logo and tried re-uploading it with the same result.osTicket version 1.10.1PHP version 5.6.31OS version Windows Server 2012
