Issue with Authorize.net AIM updating table - error 1366 incorrect integer value

[SPython]

I don't think it's a caching thing. Doesn't seem logical that a db would cache old schemas for automatic reverting.

I wonder if there's something else in your site that's making the change though. Perhaps doing a search of your entire site's PHP files for "bigint(20)" might be revealing. Admin->Tools->Developer's Toolkit->bottom field.

Nope - the only other file that contains it is authorizenet_echeck.php which I am not using and have not enabled
