Thanks for your help,
When I did the upgrade, I successfully activated and can see all my forms in the admin area.
But when I open my site and where there is a contact form, the page can not be opened, just see the name of the post. (nothing else)
I had to deactivate pluging again, that site I could normally do.
Please, do you have a solution to this newly created problem.
Thank you in advance.
Greetings CanaC
I can say that this is the best plugins for contact
I recommend everyone to use.
