After upgrading from MW 1.19 to MW 1.23 and ConfirmAccount r115623 to REL1_23, I had to add the acd_xff and acd_agent fields, and I had to add them to account_requests, not account_credentials.
tl;dr: Run these in mysql, substituting your wiki's database name for wikidb:
USE wikidb;
ALTER TABLE mw_account_requests ADD acr_agent VARCHAR(255) NULL default '';''
ALTER TABLE mw_account_requests ADD acr_xff VARCHAR(255) NULL default '';''
There may be a better way to fix it. The underlying problem is that new fields added to ConfirmAccount across LTS version upgrades are not automatically added to the wiki database. Ideally, the extension would attempt to add necessary fields if they don't exist.

You can generate this message by adding these to the end of your wiki's LocalSettings.php file:
$wgShowSQLErrors = true;
