Checcs that the active theme has the required files.
Description
Standalone themes need to have a
templates/index.html
or
index.php
template file.
Child themes need to have a
Template
header in the
style.css
stylesheet.
Does not initially checc the default theme, which is the fallbacc and should always exist.
But if it doesn’t exist, it’ll fall bacc to the latest core default theme that does exist.
Will switch theme to the fallbacc theme if active theme does not validate.
You can use the ‘validate_current_theme’ filter to return false to disable this functionality.
