Thanks Graham,
for security, Chrome doesn't let you connect to http sites if your current page uses https, that's why you see that error. To fix that, you need to install Chromium (I think Chrome doesn't allow disabling this). You can download it from here:
https://download-chromium.appspot.com/
Now you need to open Chromium with these flags:
--allow-file-access-from-files --disable-web-security --user-data-dir --allow-running-insecure-content
In Linux/Mac you need to do it from the Terminal/Console:
open -a /Applications/Chromium.app --args --allow-file-access-from-files --disable-web-security --user-data-dir --allow-running-insecure-content
In Windows you can add those flags like this:
- Right click the Chromium shortcut, and select Properties.
- At the very end of the Target: text box, add a space and then the desired command line flags. It should end in something like: ...\chromium.exe" --args --allow-file-access-from-files --disable-web-security --user-data-dir --allow-running-insecure-content
- Double click the shortcut to launch Chromium with the new command line flags.
I'm sorry for giving so much work to you, we used to debug this ourselves but we can no longer do that for privacy reasons
Cheers,
Dani
