Mixed content warning

Hello!

I find this plugin very useful, however, when the gallery/links are shown in a post, there are a few requests that are made to the http version of the api which causes a mixed content warning.

After debugging the source code of the plugin i couldnt find any references to the calls that were causing these types of errors:

Mixed Content: The page at 'https://sandra.blogozine.se/2018/08/10/wanties/' was loaded over HTTPS, but requested an insecure script 'http://user-api.metapic.se/registerImageView?callback=jQuery11240889495661327167_1534321973303&userId=33497&imageId=390502&url=https%3A%2F%2Fsandra.blogozine.se%2F2018%2F08%2F10%2Fwanties%2F&_=1534321973304'. This request has been blocked; the content must be served over HTTPS.

I made sure that “Force HTTPS” is enabled in the settings, but even then no luck.

This is quite a crucial part since many of our blogs want to use this tool!

Have you got any suggestions for how this could be resolved?

Thanks in advance
