I am having the exact same installation problem.
Everything has been uploaded to the server, permissions have been changed, language selected on ndxz-studio//install.php page. All is confirmed writeable:
OK /files folder is writable...
OK /files/gimgs folder is writable...
OK /ndxz-studio/config folder is writable...
Let's try to set up the database now.
..and so I "try to setup database now" and enter in relevant information. Database was setup by webhost and I have the correct database name, username, and password. And yet, as with others here, this message appears:
XX Please check your config settings again.
So I go poke around the config file which is called config.example.php Tried changing permissions, changing name of file with the same results as described above.
The install.php file can't be deleted until this successfully installs so that isn't the problem either.
Could use some help on this as I am doing this solely for the sake of making a tutorial video to show others how to install indexhibit, so this is a problem they may encounter and it will be good to troubleshoot this on the video. php/database geniuses out there perhaps?
Any help appreciated.
