Installing a Github copy of Prestahop, visiting the `localhost/install-dev` folder.
I fill in my working (tested) database credentials on the *System configuration* step.
I get the following error when I click Next. I can also see the same error when I inspect the AJAX request for the *Test your database connection now* button.
I googled this error and nothing relevant comes up. Is this a known issue? How do I debug?
