So yesterday i was happily editing the theme of my tumblr blog and everything was working fine. Go into same blog to day and it brings up thsi when i click save: "Un oh! We could't save your theme. Looks like your custom theme references assets from non-HTTPS Urls. Please try again using only HTTPS Urls." Super confusing because not urls have been add since yesterday and everything was fine then. Same thing is happening with my other blogs with custom themes. I even went through and deleted all the urls on the html page just to see if it would do anything and the same alert came up. What is going on ??
Please help
Cheers
Ok im a goose. Looks like tumblr has changed their requirements on http. I know it sounds obvious but i couldn't tell why it was happening on every theme apart from their default theme. The reason is you need to go in and change the tumblr links to css and java from http to https "http://static.tumblr.com/xlsgtjb/WEMoeha97/style.css becomes https://static.tumblr.com/xlsgtjb/WEMoeha97/style.css" If you still get the alert after this try searching for other urls and delete or change them to https
I have the same problem, and I thought all I have to do was changing the encryption to "Always serve blog over SSL" in the blog settings, like this: Blog settings, encryption
Apparently not, because the problem isn't just in the blog URL but also in the customization section.
So you need to enter the section, go through all the code, find the http URLs and change them into https URLs.
