Either there is a fatal PHP error which is preventing the AMP page from being processed, or you have some caching layer that is serving a non-processed AMP page.

If you’ve recently just added the snippets it may just be a matter of waiting a couple of days. As there can be a number of reasons why ads are not appearing in your AMP URLs the [AdSense Help Center](https://support.google.com/adsense/?hl=en#topic=3373519) should be able to assist. * Note also that as you’re using AMP in legacy reader mode your page content isn’t as substantial, with no sidebars or other widget positions. The AdSense logic may not find any suitable placements for Auto ads in your AMP URLs, in particular for URLs that have very little content. Most URLs I’ve checked have a couple few sentences of content. You may have better luck using one of the available core WordPress reader mode themes. * Thread Starter [Tee](https://wordpress.org/support/users/teenow/) * (@teenow) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-1406/#post-13459879) * I will just like to ask this. Is there going to be a time when reader mode can activate category pages for amp or we will have to pick other options for amp to show on category pages?? * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-1406/#post-13460038) * You can already use Reader mode with category pages now as long as you select a Reader theme other than “AMP Legacy”.
