Major Upgrade Problem - Please advise

[smooth-c]

I've just upgraded from beta4 of 3.7 and i've done everything as instructed and replaced/overwrote the existing files with the new ones and I've got this error code upon going on the discussion/install/upgrade.php path.

$errstr in $errfile on line $errline
"; break; case E_USER_ERROR: require_once(DIR . '/includes/functions_log_error.php'); $message = "Fatal error: $errstr in $errfile on line $errline"; log_vbulletin_error($message, 'php'); if (!headers_sent()) { if (SAPI_NAME == 'cgi' OR SAPI_NAME == 'cgi-fcgi') { header('Status: 500 Internal Server Error'); } else { header('HTTP/1.1 500 Internal Server Error'); } } if (error_reporting() OR ini_get('display_errors')) { $errfile = str_replace(DIR, '[path]', $errfile); $errstr = str_replace(DIR, '[path]', $errstr); echo "
Fatal error: $errstr in $errfile on line $errline
"; if (function_exists('debug_print_backtrace') AND ($vbulletin->userinfo['usergroupid'] == 6 OR ($vbulletin->userinfo['permissions']['adminpermissions'] & $vbulletin->bf_ugp_adminpermissions))) { // This is needed so IE doesn't show the pretty error messages echo str_repeat(' ', 512); debug_print_backtrace(); } } exit; break; } } // ################################################## ########################### /** * Unicode-safe version of htmlspecialchars() * * @param string Text to be made html-safe * * @return string */ function htmlspecialchars_uni($text, $entities = true) { return str_replace( // replace special html characters array('<', '>', '"'), array('<', '>', '"'), preg_replace( // translates all non-unicode entities '/&(?!' .
