image links

Hi,
I have recently installed the Stargazer Theme and love it, only problem is, I can’t get a related plugin to work properly as they don’t display images and neither does Jetpack related posts.

My image on the about author bio doesn’t work either. I have deactivated for now but even when I reactivated there was no change.

I am assuming there could be a conflict with a plugin, but I can’t see why as there are no other plugins, associated in any way to related posts or bio.

Please advise, looking forward to insight ??
