Hi,

I am also sharing my experience my about AMP, I install the AMP WordPress by Automattic on my blog Blogging World. After 4 days of Plugin Installation I see Error in my google webmaster tool that "Invalid attribute value" I do not know what is error about.

I have a question is there is some syntax or other error created by this plugin caused this error or something else ? Is there is need to install any other plugin with AMP for best performance or not ?

Effected URL showing in Google Webmaster tool:
