Hello Alfredo,
It seems you need a fresh update to the latest version of the theme. Please update your theme to the latest version.
You can follow: https://www.styledthemes.com/installing-updating-themes/
Note:Be sure to make the backup of your website or else it may be lost while updating the theme.
You better use duplicator plugin to make a backup. https://wordpress.org/plugins/duplicator/.
Incase if you want to edit the file yourself be sure to make the changes in the child theme so that changes won’t lost upon updates;
1. Go to wp-contents >> themes >> partials >> social-bar.php and duplicate the file in child theme
2. Then you can make changes
Note: To create a child theme; You can follow: https://developer.wordpress.org/themes/advanced-topics/child-themes/ or directly download from the account section.
Please let us know.
Best regards,
Bidur
