I updated my WAMP on my new Mac Mini M4. During installation the old websites were copied in the db/mysql57 and the htdocs/ directory. If I use the menuitem “My websites” on the MAMP page, it’s shows a listing of all my local websites, but unfortunately I got an “Error establishing a database connection”.
If I make a new local WP website the database is created in MAMP/db/mysql80 instead of ../mysql57 but simply copying all the local databases into that directory has no effect.
While checking the databases with phpMyAdmin I don’t see the old databases. If I create a new fresh WPwebsite in htdocs, then this site works and its database is correctly intstalled on mySQL.
I tried modifying the wp-config.ini but that has no effect.
What can I do besides rebuilding all the local WP-websites?

I have WAMP installed and I started working on my new website using WordPress and everything was great but this morning I opened my localhost/wordpress and I get the following errors. I no longerhave access to WP Amin either.
