I installed the module on my Drupal 8 site. It dit not work as it should at all. Tried with 2 simple image slides, nothing fancy, default settings, only one showed, and after a split second it was just a white block. No thumbnails. Nothing worked as it should. So I added all the support modules all over again, and removed the megaslider via the "uninstall" menu under "modules". 

When I try to add the megaslider module again now, it says:

"Unable to install Mega Slider, image.style.md_slider_thumb already exists in active configuration."

Ant wont activate. I have tried to delete the complete megaslider module folder, and copy the files all over, same happens.

Please advice.

Breg,
