If I set the DEBUG = False in
*/var/lib/mailman/mailman-suite/mailman-suite-project/settings.py* file, I don't see the pages of the applications Accounts, Admin and Hyperkitty are loaded properly. After browsing google, I came to know that the pages of CSS, js and images are not loaded if DEBUG is set false. And my webserver is RHEL 7.5 in built httpd.
Please do the needful. I am actually new to Python and doing the
risk of running customized Maliman 3 on Production.
