FAQ > I get emails containing codes such as [foobar]. What’s this? I want to see the user’s input.

I deactivated Contact Form 7, deleted the plugin and data, reinstalled and recreated the form and everything was working again. Happened on two websites on the same host.

I also tested using the demo form that came with it so it was not a mismatched field name.

Previous to this Contact Form 7 had a message that said “Contact Form 7 3.8.1 requires WordPress 3.7 or higher” when our install of WordPress was on 3.6.1. So I updated WordPress but the problem remained until I reinstalled Contact Form 7.

All is good now.
