I have created a theme by copying one from an existing site. The theme displays fine in the published website, but I can’t get it to show on Admin > Installed themes.
It’s not a major problem, since the theme works, but I’m confused why it might not be showing in Admin.
FYI - I didn’t use
bin/plugin devtools newtheme to create the theme. I just copied an existing theme that was working on another site. Is there anything I can do in the backend to replicate the actions of
bin/plugin devtools newtheme ?
