Custom validation error message not working / base cf7 messages overruled

Hi,

We have installed the Custom validation error message – CF7 module and entered the custom error for existing forms.

Only we notice that the basic CF7 are still used in the forms and not the Custom validation error messages.

Could you support us in this?

Sincerely,
Frank van Rooij
