Hi there,
I have this message this I moved my instance :
“Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.”
What I did:
downloaded nextcloud folder from my previous host
downloaded the database
uploaded the nextcloud folder to the new host
created a database and imported the saved database
It sounds you are moving from one hosted space to another. I would expect both systems are different in term of prerequisites, installed modules and versions. I would expect some prerequisits are missing on new host.
