@AltanAdacay - thanks for reaching out - I think it is the validator that failed- you can fix this by using our new boilerplate code in the head.

Follow the example - here
https://github.com/ampproject/amphtml/blob/master/docs/create_page.md

You will need to delete this code in your head
<style>body {opacity: 0}</style><noscript><style>body {opacity: 1}</style></noscript>

and replace it with the one here:

https://github.com/ampproject/amphtml/blob/master/spec/amp-boilerplate.md

I shall work with the validation team to provide a better validation error

But, the old code should still validate, no?

[camelburrito]

Yes on existing pages - (Not on new pages i guess)

@powdercloud can confirm.

This looks like a validator parsing bug. @powdercloud and I are looking into it. It has to do somehow with the multibyte characters in the body, but what's going on is still a puzzle.

[cramforce]

@AltanAdacay For you: Don't worry about it. Our server side validator validates your page and the JS validator you are using will soon as well. Thanks for posting the bug!

[AltanAdacay]

[AltanAdacay]

Thanks for everything... Yes work now perfectly

I feel nobody posted the solution.
For me it was: avoid whitespace.

I was getting this message because there was <style>...</style> block inside HTML. I replaced it with <style amp-custom>...</style> and the problem disappeared.

Hi,
On my webpage http://m.avocatferval.com/index.htm I still have the error message
"The mandatory text (CDATA) inside tag 'head > style : boilerplate' is missing or incorrect"
while I respects https://github.com/ampproject/amphtml/blob/master/spec/amp-boilerplate.md
Could you help me finding what is wrong?
Thanks in advance
Jerome

@JeromeParis you need to split your CSS into separate style tags. You have placed custom style inside the boilerplate style tag. Instead it needs to be in a <style amp-custom> tag.
