Hello guys, please could anyone of you help me with the Server error message - 0 - Call to a member function header() on null in our account? If I want to save anything there is always this message. We had a hired company that did support us, but it ended its activity and I, as a marketing person, do not know much about it. I would need to create a new page, but I’m stuck on the error page. I would be happy also if you could share any contact who can help. Thank you very much.
Did you check the logs folder as the message suggests?
not yet, I do not know where to find it. Can you direct me please?
