Problem with the relative urls

Hi,

For my website, I use a plugin called “Root Relative URLs” that converts all URL formats to root relative URL’s.

So when I try to share a post, the link inside it doesn’t show the “www.mywebsite.com” part, only the “http://” part and the end of the url.

How can I resolve that problem?

Thank you,
Thomas
