* Thanks again in advance for any comments or help on this issue
* Getting an error on google amp pages etc. and was wondering if it may be coming

* 1. The attribute ‘type’ may not appear in tag ‘style amp-custom’. (see [https://www.ampproject.org/docs/reference/spec.html#stylesheets](https://www.ampproject.org/docs/reference/spec.html#stylesheets))”
* 2. The tag ‘head > style : boilerplate’ is missing or incorrect, but required
by ‘noscript > style : boilerplate’. (see [https://www.ampproject.org/docs/reference/spec.html#required-markup](https://www.ampproject.org/docs/reference/spec.html#required-markup))”

* Just wondering if this is coming from this plugin or from the AMP plugin from

The AMP HTML format
