Error while trying to create AMP page

Hello,

i have been asked to open a ticket about this topic:

Generation of an blog entry basicly works but the google verifier throws error and complains about non-AMP format.
I suspect it coming from using mootols/rokgallery links in the articels. Which should get filtered out, i suppose.

Working Page:
http://stormrider-surfcamp.com/bali-blog/entry/uluwatu-daytrip?format=amp

(why does http://stormrider-surfcamp.com/bali-blog/entry/uluwatu-daytrip/amp NOT work? Can i make this work?)

I ask because currently all URLs containing "?" in robiots.txt are blocked and i would like to leave it that way.

Then, i would assume that easyblog also renders AMP pages not only for articels (?) but for also for component and modul output?
I cant get any AMP output from:

http://stormrider-surfcamp.com/bali-blog/
http://stormrider-surfcamp.com/bali-blog/tags
http://stormrider-surfcamp.com/bali-blog/tags/bali

etc.

And appending "?format=amp" produces

Fatal error: Call to undefined method JDocumentRaw::isHtml5() in /var/www/opt/cms/scamp/libraries/joomla/document/renderer/html/head.php on line 73

best regards,

Arnd
