Hi,
please open your page-front-page-revolution.php file
(you can find it here \wp-content\themes\evora\page-front-page-revolution.php)
and on the line 80 you have
<input type="submit" class="ss_submit" value="<?php _e('Go!', 'ABdev_evora'); ?>">
Just rename Go! to your text.
On what icons do you mean? Social icons?
Did you set all sentence search how we explain above?
If you still have issue with this you can send us your WordPress credentials so we can take a closer look.
Thank you
Cheers
