Hi and welcome to the forum! Please don’t stalk existing topics; next time create your own topic. Also, please read the issue resolution for my specific problem @EdwardHamHam also posted in that thread:

Infinity free wordpress websites are not working database is down

I was also having the same issue with my blog (which I remind you I don’t touch that much), which I didn’t resolve by changing username and password on my configuration file, but I got it working by changing my hosting account password as well to try and force the system to fix the permissions! If it doesn’t work on your end try it as well: Though the wait isn’t necessary, it’s still good measure to make sure your WordPress websites will work again. Also, make sure to update all your wp-config…

And if you need help changing your hosting account password here you go:

@JxstErg1

Log into your Client Area, go on the hosting account you’re experiencing the problem, click on “Account Change” and then “Update Password” if you agree to generate it randomly (or fill in the “New Password” field with the new password you want to apply on the hosting account before clicking that button).
