Https vs Http

I found the plugin useful as it writes in the page source code the neccesary og:image code so that facebook and other pages can grab my associated image.

What I’ve recently found (as facebook was not grabbing the correct image) was that despite my page is running under http only protocol, the og:image tag in the page source says it’s https !!!

Is there any way I can solve it ?

Thanks
