Thread:Extension talk:Survey/Exception with mediawiki 1.22/reply (3)

getPageTitle method was introduced in MediaWiki 1.23, which is still under development. Basically the newest version (git HEAD) of Survey requires MediaWiki 1.23 (or newer); try using an older version of the extension with 1.22 (and don't take the Extension: pages as absolute truth; often the documentation is more or less out-of-date, especially for extensions which have no clear "owner"/maintainer).
