Apologies for being late. When you are in editing mode, you will see two buttons (Visual and Text) to the right, above the editing window but below the page title. Click on ‘Visual’ and the image should be showing inside your editor. Let me know how you get on.

Since you are locked out, if you can access the back-end by going through phpMyAdmin, then this is another option and changing the URL manually in the wp_options table to https.

Perhaps go to the Visual mode instead of the editing mode. I can see the image in the code with the title ‘Business man and positive graph’.

Child themes are recommended if you want to modify the existing theme, so when an update occurs, it will not override the changes you made and your theme will continue to be secure. ??
