Regarding upgrade 12.0.4 to 13.0.2

Hey Dear,

Using a silent upgrade method, I have successfully upgraded SugarCRM from version 12.0.3 to 13.0.2. However, when I attempt to access it via the URL, the login page is not displaying. Upon further investigation, I noticed that several files were created in the cache/* directory, but none of the JavaScript-related files are present, likely causing the login page to not show up. Could you please guide me on how to resolve this issue?

NOTE:-
This URL is not calling Is this an issue?
