Hi there,
I have gone through the details. Just to summarize when you paste the social media links to the admin dashboard it doesn't generate a preview.
This issue you are having with the WP User Frontend plugin can be fixed.
Would like to introduce myself for this job, I'm having an 7+ years of working experience in WordPress and WP plugins with the expertise in latest technology being used i.e. PHP, JavaScript, HTML,CSS and Bootstrap. And, have worked on the similar issue before.
Please ping me with the Site URL and let's get started without any further ado.
Thanks
