Hey, I had same issues … but showing non-secure SSL image errors in browser.

Stray 192.168.0.120/wp_011_gadgets/wp-content/uploads/2017/03/53.jpg inside the latest Newspaper template. I think I uploaded the Gadgets config.

I found it by doing a select on the wp_options table:
SELECT * FROM wp_options where option_value like “%192.%”;

The above screencast screenshot from Simon C did the trick, found these references in the BACKGROUND Sign In/Join Bacground and Mobile menu/search background.

Please fix this in next pull request pls … its a tough one to find.
