Hi there,

The stylesheets sanitizer is not working properly. See the attached screenshots, the same happens in all the AMP pages.

The root of the issue is at includes/amp-post-template-actions.php.

The stysheets added by penci_amp_post_template_add_fonts action are not being sanitized the right way. If the comment the following line at the function "penci_amp_post_template_init_hooks", the warnings are gone but the pages loads without any font:

add_action( 'penci_amp_post_template_head', 'penci_amp_post_template_add_fonts' );

I tried to fix this sanitizing the CSS fonts manually with it looks like amp-custom can be added only once to the DOM. I'm not too familiar with AMP tagging.

IMPORTANT: We are using the latest version of Soledad and AMP plugin.

Let me know if there is something that we can help.

Hi there,

Those lines werent' added by us.

It happened in both websites, quiltsocial.com and knitmuch.com, at the same time after the latest update.

Check my previous comment. The root of the issue is in includes/amp-post-template-actions.php, in the following add_action:

add_action( 'penci_amp_post_template_head', 'penci_amp_post_template_add_fonts' );

This is not a support ticket :) this is just an advice.

Check both websites now:

- https://quiltsocial.com/amp/introducing-the-new-baby-in-my-quilt-life-oliso-mini-project-iron/

The errors are gone.

I just comment the line #10 at includes/amp-post-template-actions.php.

There is an error in the "penci_amp_post_template_add_fonts" function. The stylesheets sanitizer has a bug but it's looks like it's not neccesary to fonts so please bypass this in the next update :)
