I use Duplicator and install a local copy of my website with XAMPP. I get it up an running and everything works fine, but when I do changes suddenly I get a database error. (“Error establishing a database connection”).
I tried everything here: https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-error-establishing-a-database-connection-in-wordpress/, and also tried to start a new install (clean database, setting up Duplicator from scratch again). At first the new install worked, but then I got the error again.
What’s causing this? What can I do?
