Https & php 7

We have just recently updated the entire site to https & php 7.

When posting, make sure that any images that are linked are served via https or they simply won't show.

If the site only serves http then, when you click the insert image button and choose the "from url" option. check the box that says

Retrieve remote file and reference locally

and it will serve the image on our servers instead.

Or you can upload images to a thirdparty service such as imgur, which serves images via SSL (https)
