Hello @coryjames038
Thank you for contacting us, It seems you have selected only a singular support template in AMP settings which means only single pages such as single post or single product pages are being served as AMP at the movement.
Please toggle on all supported templates to make HomePage and other pages AMP.
Toggle ON “Server all templates as AMP”

Hope this helps!
Hello Milind,
How are you?
The templates is already on on serve all templates as AMP, Please check the screenshot.
Hello @coryjames038
That’s strange… Can you please re-install the plugin with the delete data option turned ON.
1) Login as Admin
2) Visit AMP->Other-> Toggle ON “delete plugin data at uninstall”
3) Click save (screenshot)
4) Goto Dashboard->Plugins->Deactivate AMP plugin
5) Click on the delete AMP plugin.
This will remove any previous data saved and settings that are saved for AMP plugin and might resolve your issue.
6) Search AMP and Click Install and Activate
7) Follow the wizard and setup the AMP plugin.
Let me know if this helps!
Hello @milindmore22
I’ve deleted with ON “delete plugin data at uninstall” and reinstalled the amp, I’ve also installed AMP Enhancer still getting same error. Please look into the matter.
Hello @coryjames038
Please confirm following:
1) please confirm you are no longer using “Sandboxing Mode (Experimental)”
2) Please confirm if you have added data-px-verified-tag attribute to the <style> tag on homepage.
if the AMP plugin detects data-px-verified-tag attribute it will keep the AMP invalidation, In your case, it will keep CSS more than 75KB, which also means the page is no longer AMP.
Hello @milindmore22
1. I confirm I’m not using Sandboxing Mode
2. I’ve not added any tag
Please do something soo that I can get AMP on all website.
Thank you
Hello @coryjames038
I am not sure what could cause the issue on your Home Page but as we checked other pages such as blog and product pages those have valid AMP but not the homepage.
Following are list of AMP tests on different pages.
1) Blog Page
2) Single Post
3) About Us
4) Product Category
5) Single Product
Sorry we can’t be more of an assistance on this one!
