Change icon via wp-admin impossible at this time. But you can change icon via edit file \wp-content\themes\oceanplaza_woo_v2.1\home-index.php
You need find and replaced in file, code <i class="icon-skype firm"> to <i class="icon-print firm"></i>
Have you any questions?
If you do not have too much trouble, could you appraise this theme on http://themeforest.net (log in, go to section “Download” and select needed amount of stars http://prntscr.com/3vxzil).
The higher rating of theme will be, the faster updates will be created.
Thanks in advance. 😉
