I had a problem with my old website some time ago and wrote a blog post about it. Now I have transferred this post to my new blog. It’s about the following error message:
The problem
I tried to load a resource from the origin of a domain, even though I’m currently in a subdomain. I’ve tried to access https://konzeptcode.com from https://ht.konzeptcode.com . This must be allowed separately.
The solution
You have different ways around this problem. If you only temporarily load the resources from there and use Google Chrome, I recommend you to install a plugin.
However, if you are always going to load resources from another subdomain, you can bypass this error message by making a change to the htaccess file.
