I am running moodle 3.11 on Lubuntu 20.04 which is running smoothly but now I want to update both moodle version to 4.1.6 and Lubuntu 22.04. I did update my OS and checked moodle 3.11 is running fine or not and thankfully it was running fine. I then upgraded moodle to 4.1.6 according to the documnetation.
- Copied moodle software folder to another location
- Copied moodledata folder
- Copied DB backup which was pgsql in my case
I then added additional plugins which in my case was autoenrol under enrol folder, vpl, virtualpc, saml2 and questionnaire under mod folder and restarted the website and page went blank.
I hadn't touched any contents of moodledata folder.
Any help ?
