WFFM Form verification does not show right error message

Question

Sitecore version: Sitecore.NET 8.1 (rev. 160519)
WFFM version: Web Forms for Marketers 8.1.rev. 160523
XM environment

I've configured a login form with WFFM.
Form Verification: Check User and Password
Save action: User Login with Password
And updated the Error messages for each language I have.

I also changed the error message, but when testing it out, I always get:

We experienced a technical difficulty while processing your request. Your data may not have been correctly saved.

In the error log I do see the translated message.

21492 14:34:15 WARN Web Forms for Marketers: an exception 'Check FR Fails' has occured while trying to execute an action ''.

Why is the error message (Check FR Fails) not shown on the front end?
I have the feeling that I'm missing something here. Perhaps WFFM wasn't installed correctly.

Answer 1

It looks like the setting value “Exception.HideInner” should be set to "false" in the \App_Config\Include\Sitecore.Forms.config in order to display this message.
