I want to use the TYPO3 forms extension with the double-opt-in extension from Lina Wolf.
I have installed these extensions with composer and added double-opt-in-template.
I created a form and added double-opt-in as the first finisher.
The double-opt-in-plugin is inserted in a typo3-folder. I use it out of the box with no individual configurations.
Submitting the form results in an email to the sender asking for confirmation or deletion, that's nice. But this mail neither contains a link for validation nor for a deletion of the request.
The translation of my German mail is:
Hello Bernd, Thank you for your registration. To confirm your e-mail address, please click on the following link or copy it into the address bar of your browser: Have you not requested this e-mail and would like to have your data deleted? Delete e-mail data completely:
What did I miss in my configuration? The documentation is not very detailed.
