Just following up – the issue looks like part of the update between versions 1.0.77.21 – 1.0.77.23
Rolling back to 1.0.77.20 fixes the issue. Delete the current version of the plugin and re-download from this link https://en-gb.ww.wp.xz.cn/plugins/accelerated-mobile-pages/advanced/
Scroll to the bottom and select 1.0.77.20 in the dropdown, download and install as normal, it will keep your settings from before.
Hope this works for you and the author updates the main version asap
Also getting this issue – “The attribute ‘for’ may not appear in tag ‘amp-img’.”
This is repeated for several other words on the page.
The issue seems to be on the data-hero and fallback attributes, I can’t yet see why but it looks like the html from the plugin is malformed somewhere, either missing a closing tag or quotations around the data-hero and fallback area.
