Using after_switch_theme will activate the theme (which is fine as we want to run the check within the context of the new theme). If the dependencies are not fulfilled ($missing_dependencies = true;) we’re instantly switching back to the theme previously used (passed via after_switch_theme and $oldtheme). add_action( ‘after_switch_theme’, ‘check_theme_dependencies’, 10, 2 ); function check_theme_dependencies( $oldtheme_name, … Read more

We are using this wordpress plug in – New User Approve Provides functionality to approve/deny new user registrations.
The reason that the plugin activation hook wasn’t working in the code provided in the question is that on plugin activation the plugins_loaded hook is never run.

Don’t do the check on activation? Seriously, the best way I can think of is not to check for this on activation, but only in the normal plugin load process. And instead of throwing a warning (I assume you mean a PHP E_WARNING), perhaps putting an admin error box up would make more sense.
