Now I got past the database errors, and when I open the http://localhost/OpenCATS in a browser, I do not get the installation wizard, but a bunch of the following warnings then the logon screen:
Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in C:\xampp\htdocs\OpenCATS\lib\DatabaseConnection.php on line 321
It does seem to create some database tables. But the install wizard, test connectivity, etc. didn't run.
Help would be appreciated. Thanks!
Note: I installed XAMPP-windows-x64-7.2.33-1-VC15
