Fatal error

@Eldorean

Thank you for the reply. Upon checking the info the prefix of the table matches my old database. Upon checking the tables in the database I see that old posts are erased and are replaced by the sample, hello world, etc. only 5 posts are there while it should have been 20 or more.

Please make sure to check the old database, not the new one. If you checked one database and only found the default posts, please check the other database instead.

@Eldorean

Could it be that new installation wrote over the old database and is now erased?

It’s not impossible of course, but extremely unlikely. Softaculous wouldn’t do this (it always creates a new database), and you’ll have to jump through hoops to do this with WordPress’ own installer.

@Eldorean

And can my backup wp-content folder do something in that case?

Not really. All posts, pages and settings are stored in the database. The wp-content folder only contains plugins, themes and uploaded files. And plugins and themes are often easy enough to just reinstall. If your database was lost, and you don’t have a backup, then you cannot restore the site.

I checked and there are only 2 databases, the 2nd doesn’t have any table. It seems I will have to rebuild everything from scratch.
Anyways, thank you very much for your support!
