I’m sorry that I have to ask you about this again after such a long time! But now do I have some time to develop our ticket system further.
I still have the problem that the logo is not printed, but I also noticed that avatars are not printed either. So I assume that the error is not with you but with an authorisation problem or PHP extension!
I host osTicket on a Synology RS and apart from the printing everything else works fine.
osTicket v1.17 // osTicket-1.17-Awesome-102
PHP 8.0.17 // MySQL 10.3.32 // Apache/2.4.51 (Unix) web server
PHP extensions: gd, imap, intl, ldap, mysqli, phar, zip, zlib
Greetings,
Markus
