Moving from HTTP to HTTPS

I am trying to move across to HTTPS and am having an issue with mixed content in theme_mods_sydney to get the “green padlock” in Chrome etc. I can see the front page header images start with http in theme_mods_sydney in my SQL database. I have tried to change this to https and I have removed the domain name to start with //. When doing either of these, the site returns to the default theme state.

Is there something I am missing or doing wrong here?


Can’t test this right now but there isn’t much we can do about it unfortunately. The option for image uploading in the Customizer is a core WP option. The theme isn’t defining it.
What you could do is check out slider.php, copy the sydney_slider_template() function (it’s pluggable) and overwrite it from a child theme. Then hardcode your images directly without protocol.
