It came after some migration - now it supposed to be resolved.
No difference for me - I have changed the password on Wp-config file to the password same as Login to your account - InfinityFree l but it didn’t make any difference - still the same error. So I return the initial details

Did you check if your database is there under the db section in vPanel? During the recent outage some have got deleted. Make sure the credentials are correct. Also your public IP is exposed. Pls, remove that now.
I checked your account and there are no databases there. That most likely means these databases were corrupted and lost.
If so, there are no credentials you can change to fix this. Unless you have a backup, your best bet is to remove this site, reinstall WordPress and rebuild it by hand from there.
We all terribly regret what happened here. But unfortunately, this isn’t something anyone can just “solve” and make everything like it was before.
