I am experiencing the same issue with my amp site! Have you found the solution @zayan77 ? @ahmedkaludi kindly help ??

Issues are – 1. The parent tag of tag ‘html’ must be ‘!doctype’.2. A mandatory AMP HTML tag is missing from this document. 3. Tag found outside the document head which is only allowed as a direct child of the document head. 4. Only amp-boilerplate and amp-custom ‘style’ tags are allowed, and only in the document head. 5. Custom JavaScript is not allowed. 6. Tag or text which is only allowed inside the body section found outside of the body section.

Total 17 pages are affected as of now! Being a non-techie I am completely clueless .I updated the plugin last week and since then I have been experiencing this issue.

Thanks,
Ana
