Error Msg on /amp page version

AMP plugin does not support ‘pages’ only ‘posts’ — at this time.

If I misunderstood your error, apologies.

Thank you for your response. This is for a post.

Make sure you
a) save permalinks
b) try clearing transients with wp-optimize

If still does not work, try temp disabling any compression/optimization plugins that rewrite pages — some caching plugins need to be setup to work with AMP as they try to compress the AMP page breaking it.

So, if using a caching plugin, be sure to see help info for that cache plugin as far as using with /amp/ .
