although in the settings all is fine
grafik

Any idea how to fix it.
(The version is the latest stable one 12.10.8)

hmm i don’t know of a contact form in XWiki. Where is that?

Thanks

I used the extension from ^the extension repository: Contact Page 1.0 from Djebloun Sidali.
So far I found that this uses the old kind of captcha. How to contact the author?
Thanks

I have the same problem as you. Were you able to find a solution?
