Hello

I installed "Contact Form" but I have this error message :
Warning: Mailer Error: Could not instantiate mail function. in /homepages/35/d693484988/htdocs/clickandbuilds/Piwigo/include/functions_mail.inc.php on line 923


I just ran a series of tests:

-1- I set an email address hosted on my hosting server as the administrator (and therefore, the address for receiving form submissions).

-1A- If I don't enter a sender email address in the form (and I've configured it so that it's not mandatory), I receive the email correctly.

-1B- If I enter any sender address (Yahoo, Gmail, or many others): error message.

-1C- If I enter a sender address that is another email address hosted on my hosting server: I receive the email correctly.

-2- I set my yahoo.fr email address as the administrator (and therefore, the address for receiving form submissions).

-2A- If I don't enter a sender email address in the form (and I've configured it so that it's not mandatory): error message.

-2B- If I enter any sender address (Yahoo, Gmail, or many others): Error message:

-2C - If I use a sender address hosted on my hosting server, I receive the email correctly.


Any idea ???
