On beres-expert.heliohost.org, Contact page, I have set up a box where someone can write a message and by clicking the button below it, the message should get sent as an e-mail to an e-mail adress, using php mail function. Unfortunately, I receive an error, 500 Internal Server Error. I tested this script on another hosting server and it worked. What can I do to fix this?
I await your answer,
Thank you
