Instructions in this section are common to both new installations and upgrades, and should be applied after completing either process.
Test your configuration
Load up admin/check.php to validate if everything is setup correctly.
NOTE (for PHP 5.2 only): check.php sometimes reports the value of register_globals incorrectly. To confirm the correct value, Create a page with this line in it:
<?php phpinfo(); ?>save it with a .php extension and load it up in your web browser.
Delete the admin folder
For security reasons, the scripts within this directory should not be accessible on a live MantisBT site or on any installation that is accessible via the Internet.
Once you have confirmed that the install/upgrade was successful, you should delete this directory
rm -r admin
