I will try to be as clear as I can, as English is not my mother tongue
After reinstalling my macOS, I wanted to reinstall on flywheel the website I was working on (last backup was in October 2018, don’t remember which configuration I choose).
When I import the site using File > Import site, a message tells me: “Your wp-config.php file has an empty database prefix, which is not supported.” I tried to change my new wp-config.php by the old one, and I get into the WP dashboard. The problem is that I no longer have my media or the pages I made.
I have all the files and a backups folder with the sql database. But this one is a zip file which decompresses in cpgz, very light file of 143ko.
I tried to go through the terminal that announces that “the specified directory is not a mydumper backup” and tried several decompression software but nothing works.
I also tried to move this file in a sql folder placed in the app folder without success. Same thing when I try to import the sql file in local admin, it shows me: “Error in the query (1064): Syntax error near ‘PK’ at line 1”.
During the installation I tried several versions of mysql (5.5, 5.6, 5.7) without success. I also tried to create a site with the same name to replace it with the old one. I read several posts in wordpress and flywheel forums and I really think I have tried everything.
Do you have a last suggestion to restore this site?
Thank you in advance for your attention and help.
