Hello,
I was able to solve the problem. I did it manually.
First created a new empty wordpress site.
Then replaced the content of the site with the content of the webspace of my existing site.
Then I customized the wp-config.php file with root/local/localhost.
And in a new “sql” folder copied the database of my site.
So I could access phpmyadmin in Local. In it I imported the content of my database. Then I deleted the content of the local database and copied the content of my database into the local database.
Now I was able to start the site locally via Local and dial into the backend of my site locally.
Everything works now.
Regards from Hamburg
