Sitecake has been working great, until a client notified me that they started getting a blank white page after entering password.
To fix the issue I tried deleting all sitecake files and uploading the latest version. However the same issue remains. Ater entering the correct password, it advances to a blank white page.
Edit the config file to put it into debug mode. Then it will show an error message instead of a blank page. That will help figure out the problem.
You could also check sitecake-temp/logs/sitecake.log.
It could also be that configuration changed on your client’s server. You can check pre-requirements by going to yourdomain.com/sitecake//config/check.php
