You are using a version of AbuseFilter that is intended for a newer version of MediaWiki. I remember that you said you're running 1.26, which is EOL and no longer receives support or updates for security issues, so I'd recommend updating to at least 1.27. But regardless, you should download a copy of AbuseFilter that is intended for 1.26.
