Hello Vesa-Pekka, thanks for purchasing Thefox!

We disabled the front-end editor because we use a different bootstrap and some of our custom modules doesn't execute correctly when used from the front end.

If you want to still use the front end go edit the thefox/functions/vc-functions.php file and remove the line 19 to 22 :

function rd_vc_remove_frontend_links() {
    vc_disable_frontend(); // this will disable frontend editor
}
add_action( 'vc_after_init', 'rd_vc_remove_frontend_links' );

This should do the trick.

Do not hesitate to contact us if you have more questions.

Have a nice day!

Regards.
