Languages Not Implemented in X Pages Not Working

HTTP 500 errors arise when visiting, e.g. Reports:Tasks not implemented in Tcl. (h.t. Dkf) --Michael Mol (talk) 13:45, 1 April 2013 (UTC)

MultiCategory Search extension is likely broken in MW 1.20. --Michael Mol (talk) 13:45, 1 April 2013 (UTC)

Solutions

Try to replace with Semantic MediaWiki queries. (Anyone can give this a shot...leave details of attempts here.) --Michael Mol (talk) 13:45, 1 April 2013 (UTC)
If replacement with SMW queries doesn't work, I'll dig into the error logs this evening and see about fixing the bug. --Michael Mol (talk) 13:45, 1 April 2013 (UTC)

Account Creation Not Fully Functional

Some attempts to create accounts (even by me, while logged in as an administrator account) fail with "Login error Incorrect or missing confirmation code http://rosettacode.org create account". Clearly, this doesn't happen to everybody; new accounts are created every day. --Michael Mol (talk) 13:45, 1 April 2013 (UTC)

Details

This predates the upgrade to MW 1.20, and looks more likely to be related to the CloudFlare deployment. --Michael Mol (talk) 13:45, 1 April 2013 (UTC)

Solutions

I need to check the firewall logs to see if I'm blocking interactions between RC's server and ReCaptcha. --Michael Mol (talk) 13:45, 1 April 2013 (UTC)
It might also be a caching issue, if ReCaptcha's servers are making a query against RC's server (via CloudFlare), and getting a cached result back. --Michael Mol (talk) 13:45, 1 April 2013 (UTC)
