Some images not being serve over https

Hi,

On some pages of my site, some images are not being served over https. Getting the error message – This request has been blocked; the content must be served over HTTPS. Have only had this problem since BWP installed (deactivating the plugin is no help for troubleshooting as the whole site breaks, despite clearing all caches afterwards).

Here’s a page with an example. You’ll see the broken link to the left of the ‘growing your business’ headline. What’s strange is that it’s only some images that are still being served over http. I have tried uploading new images, but it’s still pointing to the old URL (and I have flushed the BWP cache, the page and object caches and the browser cache).

Hope you can help.

Cheers,

Sandra
