Deployed turnkey-mediawiki-12.0-squeeze-x86-ovf.zip with no problems. I went to access the Special:Import MediaWiki page which gives an HTTP 500 error. Fresh deployment, import attempted from default admin account. Tried again on a second fresh VM, same results. IE shows the 500 error, FF shows a blank page.
Deployed turnkey-mediawiki-11.3-lucid-x86-ovf.zip as a test, and import works fine.
Can't find a specific error in the logs to associate with the 500 error. I would prefer to run the v12 package, but require the import function to work. Help?
