I just installed a Hestia control panel 1.4.2 on a new Hetzner Debian 10 server and logged in and changed the theme from dark to default. I then changed the admin user ssh access from nologin to bash. I then clicked Files, /usr/local/hestia/web/css/src/themes/default.css to open the file. I then changed line 166 to change the background color from #FFF to #EEF. I then saved the file. However, when I re-opened the file, the change I made was not shown.
How can I make changes on CSS files with the Hestia file manager?
Also is this the correct CSS file to change the appearance of the admin control panel when the theme is set for Default?
