My license has expired last year and never automatically renewed. I did see this was resolved in a new update however it states that my maintenance plan has expired when I try to update this hotfix. So I am unsure what to do if I cant refresh this license key info.
Hey @nerminat0rrr
What version of 3CX are you running?
If its older than 18 U8 you'll have to update preferably to 18 U9 but if you want to get the latest features available, which you ought to, I strongly recommend upgrading all the way up to v20 U2.
In that case best course of action would be to take a backup, uninstall, install and restore.
For steps on how to install just login to our customer portal using the email you see in your license key information, in "My Systems" search for the key and then hit "Install" and follow the steps for "Self-Hosted"
