Thread:Extension talk:InputBox/Fatal error with InputBox.hooks.php

Just finished updating to MediaWiki 1.24.2. InputBox got updated with it (although despite downloading the latest version again, deleting the old one in my extensions folder, and uploading the new one, the version number in inputbox.php is still 0.2.0), but when I try to go to Special:ConfirmAccounts, I get this:

Fatal error: Call to a member function getText on a non-object in /home/myfolder/public_html/wikific/extensions/InputBox/InputBox.hooks.php on line 23

Line 23 is this:

So if there's something wrong with this line, I don't know what it is. Help?
