We need tu use captchas on our tiki (21.1 at the moment, not updated to 22 due to php 7.4 problems impeding local testing)
it seems that there is a bug since tiki18: when using captcha, there is always an error message:"!invalid empty CPATCHA value", and no message is sent.
this can be seen there:
And we don't want to alternatively use a tracker contact form, for many reasons.
Anyway, is this officially a know bug?
How could this issue be solved? The contact form is really important for many organizations, this is indeed a basic fonctionality, how is it that this issue is unresolved for so long?
thanks for your help.
