First, you need to create a Tag manager (Container ID) :
Create the Google Tag Manager container at:
Then you should create separate containers for the standard WordPress site and the AMP version.
Creating the AMP container then you must choose container type= “AMP”
When creating the container for use with the NON-AMP then you should create a container type= “Web”
This means there will be different “container” / “container type” and different tags for the AMP and the non-AMP version of the site.
If you are using the Non-AMP container ID in AMP also then this error will appear.
If you don’t know how to generate container ID in AMP then follow this tutorial.
That’s it for this tutorial!
We hope it helped you. If you have any feedback or questions, then please share them in the comments section below.
I have installed the GTM container for AMP in the plugin as it appears in your post.
But, when checking it with the GTM debugg extension the container doesn’t show up. I have looked at the source code of the page and it does not appear. Has it ever happened to you? What could be the reason for not picking up the container?
Thank you very much
