SSL-Links for Grace Themes

Hello Support Team,

first of all, thank you for your work and your fast response to the asked questions. I hope you will be able and find a resolve for a minor problem at this time.

I am using the Power Club WordPress Theme for the site https://inklusivessegeln.org
It’s a german non-profit-organisation with the goal people with and without a handicap get together for sailing and teach them sailing skills.

All was done and the site is online. Our Provider got us a SSL-Certificate for the site and it is working. My favourite browser is firefox. And as it will be, the lock symbol shows a warning sign. So I checked all links to the media I uploaded and my coding, everything was properly coded with https-links. Only the links to Grace Theme as shown in the tab “Our Themes” and in the boxes for the support groups and the documentation are http-links.

Are you able to fix this with a patch? Or is there a file, a line of code, that could be changed?

Best regards
Thomas
