Hello everyone,
I’m trying to update my Invoice Ninja installation from version 8.35 to version 5.11.66. The installation is running on Proxmox with a TurnKey installation and mostly works fine. However, the update does not work, and I get a 500: Internal Server Error.
What I have tried so far:
• I have made several update attempts through the Web UI, but without success.
• I have increased the PHP memory limit to 4 GB to ensure it’s not a memory limitation issue.
• I have checked the log files, and although there are some minor issues related to middleware and routine tasks (like currency updates and autobilling), I didn’t find any critical errors that might be related to the update failure.
• I have deleted cache files and run the php artisan clear-compiled command, but that did not help either.
Another point: the email sending is not working for me, but I planned to address this after the update.
Has anyone encountered similar issues or can anyone provide tips on how to successfully perform the update?
Thanks in advance for your help!
Best regards,
Chris
