Upgrading broke my site

[notset4life]

Was trying to upgrade from 1.5 to 1.51. Shouldn't have.

www.shopcybermidi.com

500 internal server error

Can't get into Admin, keep going to "install page"

Can you please pm me so you can take a look at my site and see where I messed up? I never had a problem with an upgrade, but if i can't fix this, I'm basically out of business. I'm not sure if the htacess files and configuration files are correct.

$t1 = parse_url(HTTP_SERVER);$p1 = $t1['path'];$t2 = parse_url(HTTPS_SERVER);$p2 = $t2['path'];

define('DIR_WS_ADMIN', preg_replace('#^' . str_replace('-', '\-', $p1) . '#', '', dirname($_SERVER['SCRIPT_NAME'])) . '/');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_ADMIN', preg_replace('#^' . str_replace('-', '\-', $p2) . '#', '', dirname($_SERVER['SCRIPT_NAME'])) . '/');
define('DIR_WS_HTTPS_CATALOG', '/');

Is that right for the new versions...or should that have been replaced with the install?

thanks
