Hi–AMP is a very particular subset of HTML with its own unique requirements. We include <noframes> tags for sake of old browsers (including email clients) and some search engines that can not (or will not) render the iframes necessary to display the slideshow. The noframes are disallowed in AMP, so that’s why you’re getting the error.
To make a site fully AMP-compatible, you may need to do some front-end filtering and reconfiguration of your WordPress website anyway. If so, stripping the noframes tags could be a part of that.
It would also be possible to customise the plugin to not include the noframes tags if a checkbox in the options were ticked (or un-ticked). If you do go about making this customisation, please consider contributing that bit of code back so that I can integrate it into the plugin and others can benefit.
Hi @flgirl – you will hopefully be pleased to hear that with release 2.4.2 we have converted the noframes tags to noscript tags, making the embed fully HTML5-compatible without sacrificing support for displaying a simple link on older browsers and email clients.
