Installation Fail

How can I manually install when the automatic installer won’t work? All of the requirements are checked off on the first page, but it fails after inputting my database info.

Well are all the database credentials really correctly entered?
I’ve installed Osclass 3.9 numerous times, for clients and for testing when addding new features, haven’t had a single problem.

If you really want to ‘manually’ install, you need to import database files in “oc-includes/osclass/installer”, rename config-sample.php to config.php and alter it based on your site.
