Thanks for the update. The “No anchor element found” console error can appear in many cases, I have it on one site although it doesn’t stop Auto ads from appearing. In some cases it can be due to document formatting, there’s an open GitHub issue on this below:
https://github.com/ampproject/amphtml/issues/26734
Note that if you have multiple ad units appearing on a page AdSense may determine there are no additional suitable placements for Auto ads, and some of the ads I see on your site are Auto ads (see here one example)
And how do I insert the amp stick script in the head ??
The plugin inserts all the required header scripts once any related body markup is found. If you’re referring to sticky ads you can paste the example body code into your site from this playground and you’ll notice the required header script appearing.
I’ll close this now as Auto ads are appearing. Be sure to checkout the different reader mode templates and reach out if you have any further plugin related queries.
