Wikimedia Bugzilla is closed!

This site, https://wiki.transitionnetwork.org/ is running on amd64 Debian Wheezy with Parsoid installed using apt as per the instructions at https://www.mediawiki.org/wiki/Parsoid/Setup#Ubuntu_.2F_Debian_on_amd64

Today the new GPG siging key was installed and Parsoid updated (see https://trac.transitionnetwork.org/trac/ticket/692#comment:103 ) to version 0.1.15 and this has caused all edits using the VisualEditor to generate 500 errors, this is what is logged when you try to save a page:

The error presented to editors is:

Error loading data from server: parsoidserver-http-bad-status: 500. Would you like to retry?

I have reverted to the old version of parsoid to get around this issue:

apt-get install parsoid=0.1.12
