you need to debug a bit, try deactivating plugins and change themes to verify those are not causing the problem.

Are you running a cache on the site?

@r-a-y, that appears to have done the trick. Great, and thank you!

add_filter(‘show_admin_bar’, ‘__return_false’);

In that code your '‘s look wonky.

Try

add_filter( 'show_admin_bar', '__return_false', 99 );

I’ve also put a high priority on it to make sure it gets done ( a priority of 99 ).
