I have performed an upgrade from may 3.14.1 Matomo to the latest version. I have Matotmo it running on my VPS (debian) for many years. Made a backup from the most important files and the database. Than get the latest zip (Wget) and copied that over to the folder where I have the older version /usr/share/matomo . When I go to the matomo/index.php I get this major error. Which I do not really understand.
In the folder /usr/share/matomo there are two symlinks is that ok?:
/usr/share/matomo/

Any suggestion how to get things going again? Thanks. Do I need to remove the symlinks? Or have other links in stead?
Nice 
I solved it myself. By removing the symlinks to the older dirs. And copy over the config.ini.php to the new config location. After that it is working again. Although I do not see any site visitors or actions right now. Must be patience I guess.
