i confirm, update ispconfig3.1.13 (work web interface) to ispconfig3.1.14p2 not work interface. ubuntu 19.04 server php7.3 apache2 before update i have copy the file /etc/apache2/sites-available/ispconfig.vhost . after update to 3.1.14p2 , i have restore old ispconfig.vhost in /etc/apache2/sites-available (ispconfig3.1.13) in ispconfig3.1.14p2 and interface web(panel) work.
The problems arise because you do not use SSL for the Interface and we are using stricter security settings now which fail when SSL is missing. You should really secure the ISPConfig interface with SSL as it's standard in ISPConfig and you will not have such issues anymore.
i'm use ssl for ispconfig interface local server, "https:...:8080" in version 3.1.13 work , in update version 3.1.14p2 not work interface. login ok and not charge web interface. does this problem depend on a non-accredited ssl certificate?
Then your problem is not related to this thread at all. You should better have made your own new thread. No. Please post a screenshot of how it looks after the login.
