In the process of creating new software and websites, I thought it might be a good idea to improve this site by changing from http to https. This is what I found I needed to do:
First make sure my hosting account had the necessary security certificate – D9 Hosting were on the ball and made their necessary changes within minutes after I raised a low priority ticket asking for help.
Firefox and Microsoft Edge still weren’t at all happy – saying website was insecure. So my third step was installing the WordPress plug-in Search and Replace This allowed me to change all instances of ‘http://’ to ‘https://’ for all of my posts and pages. There were hundreds of these – one for each image.
