Masacote is seeking help with two issues on their Discourse installation.
Editing the Welcome Message: The welcome message at the top of the page can be edited by navigating to Settings -> Customize -> Components -> discourse-search-banner and changing the headline and subhead text in the ‘Theme Translations’ section.
Switching Default Theme Mode: To change the default theme mode from Dark to Light, keegan suggests two approaches:
For individual users: Go to Profile Icon -> User icon -> Preferences -> Interface and switch the theme to ‘Light’.
For all users: Navigate to Hamburger Icon -> Admin Settings -> Customize and change the default theme from Dark to Light. Note that automatic dark mode switching may be enabled, which depends on the computer’s selected theme.
2- My forum starts automatically in DARK mode, how do I start it in primary LIGHT mode and secondary DARK mode.
for the moment I had to disable dak mode as it ended up being the main one.
