When I paste blockadblock script in my blogger theme, then this error is showing while saving theme , what’s the solution for it
This is a common error.
You can do two things to ensure this problem don’t arise again.
Make sure all the URLs used in the theme file should be https and not http.
Or You can simply remove http:// from all website links.
For eg. Change http://www.example.com
or simply www.example.com (This would be recommended)
In the other post, you asked the same question, check that I have told you to share the code of ad script.
