Solved by Free Virtual Servers tech support. Thanks!
I’ve done that already 🙁 I downloaded WordPress again, edited wp_config.php again, deleted all the previous files, and uploaded new ones.
No luck 🙁
I’ve come in desperation after trying several different things. I also deleted and recreated my SQL database.
Anything else I can try? I fill in the username, password, etc. in wp_config.php, but tend not to mess with the advanced options…
