I was updating to CE 6.5.23 via the Update Wizard. The update went without any issues. However, opening the page I get the correct login-Site but when entering the username and password, I get the following error message:
Fatal error: Call to undefined method User::findUserPassword() in /home/xxx/www/crm.xxx.com/sugar/modules/Users/authentication/SugarAuthenticate/SugarAuthenticateUser.php on line 58
Line 58 reads:
"$row = User::findUserPassword($name, $password, "(portal_only IS NULL OR portal_only !='1') AND (is_group IS NULL OR is_group !='1') AND status !='Inactive'");"
Any ideas how to fix it?
