Edit Sign Successfully Page

I copied wp-content/themes/campoal/sign-successful.php
to
wp-content/themes/campoal-child/sign-successful.php

for template override!

Then one can modify sign-successful.php in order to erase facebook share part, social buttons etc.. I tested it, works!

There is a similar php-script in
wp-content/themes/campoal/templates/sign-share/sign-successful-modal.php

which maybe must be adapted too for modal views.
I hope Long Ha can give us a hint in which cases sign-successful-modal.php
plays a role.

Kind regards
Volker
