contact-form: Template «» couln't be found

Question

I'm trying to get contact-form plugin working.

When I add the default script and send the form I get this error:

craft\web\twig\TemplateLoaderException: The template «» couldn't be found. in /vendor/craftcms/cms/src/web/twig/TemplateLoader.php:116

I use the regular unaltered script from the rpo:

<form method="post" action="" accept-charset="UTF-8">
    {{ csrfInput() }}
    {{ actionInput('contact-form/send') }}
    {{ redirectInput('contact/thanks') }}

what seems to be the issue here?

Answer 1

Somewhere, somehow, you are trying to call a template named «». That obviously doesn't exist.

Which means you need to track down what is trying to call that "template". It's very hard to say from here, the example form code that you included would not trigger that error on its own.

In your stack trace, on line #7, it seems that the hybridinteractive/craft-contact-form-extensions plugin is getting involved. Poke around the settings for that plugin, perhaps you'll find something.
