The changes from English to Kannada have been discussed. In the discussion, it has been explained that current English logo and namespace have to be replaced with Kannada. You can see ವಿಕಿಕೋಟ್ text in the discussion.
That was supposed to be the page for Village pump in Wikiquote. Since it was created previously few years back, I posted the discussion on same page. Thank you for pointing it out, I've moved it to correct page now. :)
Can we go ahead now? Its been quite some time.
We've had this issue a couple of times, so this time I asked for help from bblack (ops varnish person). It turns out you have to run this command in eval.php:
SquidUpdate::purge( array( 'https://www.wikimedia.org/static/images/project-logos/knwikiquote.png' ) );
Note the www.wikimedia.org - varnish normalises the static images to use that hostname, purges for them don't work against other hostnames.
Unfortunately, there's another step that I missed to get this image actually included on wiki pages (the knwikiquote.png image file existed, but it's not actually used by the configuration yet)
