Thread:Project:Support desk/error in extension code/reply (2)

The error message is self-explanatory: Warning: Missing argument 3 for SpecialVersion::listAuthors, called in /home/u343696101/public_html/extensions/ExtensionStatus/SpecialExtensionStatus.php on line 217 and defined in /home/u343696101/public_html/includes/specials/SpecialVersion.php on line 860

What's the question, anyway?
