I've had a screwup on my LAMP based site where a certain string value that's posted to the site from a form, was not being stored in the db. The db column for it was an enum but it needed to be a varchar. Strangely mysql didnt throw an error when running the INSERT sql from the site's PHP code. The mysql bin logs were not enabled, so I can't use that. I was thinking maybe the Apache logs, but that doesnt seem to have the POST data.
Is there any possible way to recover this? The OS is ubuntu 12.04
