I used the contact plugin for some time on a
2009-12-25b "Lemming"
dokuwiki and it works fine.
Now I get spams quite often und found the moderncontact plugin:
https://www.dokuwiki.org/plugin:contactmodern
It is meant to work very similar to the original one, only it allows recaptcha.
So I installed 'moderncontact' (and deactivated 'contact') and configured it with a recaptcha key.
BUT now the page renders only a media icon with the name 'contact' and not the form.
Switching back to 'contact' and deactivating 'moderncontact' works fine.
What can be the cause of the failure?
