Hi
Okay for this I have already given code and was working at that time. I wonder how it stopped working, but I have rewritten the code and the issue has been fixed now.
This is the updated code:
<script>
jQuery(document).ready(function($){
jQuery('#vibe_bp_login span').removeClass('si').addClass("fa");
jQuery('#vibe_bp_login span').removeClass('si-facebook').addClass("fa-facebook-square");
});
</script>
To fix the alignment:
Please add the custom code to
Wp-admin > Appearance > Customization > Custom Css > Publish
#vibe_bp_login span {vertical-align: bottom;}
