Site recently converted to use SSL. External links from a page template all use https:// protocol even though template changed to use universal // prefix (it was previously http://).
The Non-protocol URL is based on your current website, for example: https://www.worcestershireopenstudios.org/artist/cherrie-mansfield-2/ this page is using SSL Protocol.
I suggest you try these: 1) If the URLs are all in your website, use the non-protocol URL. Then it will be adjusted according to your website settings.
2) If the URLs are linked to outside of your website, don't use it, since you can not control other website.
