Our wiki is running on MediaWiki 1.31.7 and using Collection 1.7.0 (af3a0b8) 14:23, 15 April 2018. The Download as PDF is constantly failing and directing the user to Reading/Web/PDF Functionality which doesn't specifically address the reason for the "Book rendering failed". Reading through Talk:Reading/Web/PDF Functionality doesn't clear up the situation much either. It does seem to indicate there is a new render server available at https://pediapress.com/collector but that doesn't seem to work for non-Wikipedia sites. The existing render server https://tools.pediapress.com/mw-serve/ does seem to still active.
Is the functionality via this extension dead for low traffic sites that don't need or cannot install (i.e shared hosting) their own PDF server?
