Thanks so much Rene Hermenau for the great and humble response.
I have had to go to the template-functions.php of the plugin and substitute the ‘#’ for my targeted URL to make it work. Though, I was thinking this may change in any future update.
Seeing your humble response, I have had to go and change the targeted URL back to # so that you can see the error I was talking about.
Likewise, the Facebook button was not giving a popup like the twitter button, but just opening in new window while trying to share.
Furthermore, the recommended Yoast Bitly URL shortening plugin didn’t work when I set it up but the Mashshare URL shortening was working. As a result, I think it would be very helpful if the Bitly shortening could be integrated directly with Mashshare instead of having to go and save the Yoast code in wp-config.php
As for the website where I am having the issues, here is it:
