Welcome to the InfinityFree community forum! Good to have you here.
Most people answering here are volunteers. They’re often the fastest source of help. Admin (the only staff member) checks in about once a day for issues on our end.
Volunteers can’t see your account or website. Share what you actually see, like error messages and what happens when you try something. That’s more useful than your theory of what’s wrong.
AI tools often get InfinityFree wrong. If a volunteer’s advice differs from what an AI told you, please try the volunteer’s suggestion first.
Solving an issue is a joint effort. Try the suggestions you get and report back what happened.
Beep boop, I’m a bot! I dug through the forum to get you started. I sometimes get things wrong though, so do with this what you will until a human has a look.
I can’t help with this one, and a person needs to look at it. The control panel isn’t hiding the database. The lookup of your account shows it has no MySQL databases listed. Whether the original wp407 database still exists on the MySQL server, and whether it can be reattached, takes access to the account and server that only staff have.
You asked whether creating a database with the same name is safe. I couldn’t find anything that says it is, or that it would reconnect the old data, so I wouldn’t try it. You also said you want to keep every existing table. For that reason, leave wp-config.php alone and don’t create anything until someone has looked.
Your downloaded file backup is a good thing to have. Make sure it also gets you a database export, if you can still get one by any route, since the files alone don’t contain your posts and settings.
The username style suggests that this is an older database created by Softaculous.
Softaculous has historically had issues with creating databases that would not appear in the control panel or members area. Fortunately, that’s very simple to fix.
Just create a new database from the panel with the same name as your target database. The system will identify the database that already exists and fix your access to it, no data will be lost.
