I still can login and run the administrator page but the site itself is dead.
Any help?
This is what I did:
1) Create Akeeba backup
-> ok
2) Update PHP from 7.3 to 8.0.2
-> ok
3) Clean cache
-> ok, site is up an running
4) Live update Joomla from 3.9.16 to 3.9.27 (which triggered another backup beforehand)
-> I lost the internet connection at 86,3%.
Now the site showed HTTP ERROR 500.
I still have access to the administrator page, therefore I first checked the database:
5) Extensions -> Manage -> Database
-> shows a couple of errors
6) In that page I used "Fix database"
-> ok, the errors are gone
Version of the database schema (in #__schemas): 3.9.27-2021-04-20
Update version (in #__extensions): 3.9.27
Database driver: mysqli
187 database changes were checked.
216 database changes had no effect on the structure of the database tables and were therefore skipped.
7) Test https://landfrauenhd.de/
-> failed, still shows HTTP ERROR 500
Test https://landfrauenhd.de/dummy-> surprisingly this is somehow ok, as I got the 404 error page which included the overall layout with heading, colors and title pictures of the site.
9) Now I downloaded Joomla manually and started manual update which quickly went to 86,3% continued and ended shortly after that.
-> ok, I got a nice success message but a couple of warnings of this type:
Update of Manifest-Caches failed: The extension „plg_content_fields“ is not installed yet.
10) Test https://landfrauenhd.de/
-> failed, still shows HTTP ERROR 500
11) Test https://landfrauenhd.de/dummy
-> failed, and surprisingly the response is different than before:
