Здравствуйте, я пытаюсь сделать сайт только для членов, я пытаюсь создать сценарий с сессиями и т. Д. Однако, когда я нажимаю кнопку входа в систему, я получаю следующую ошибку:

Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

Fatal error: Unknown: Failed opening required 'prepend.php' (include_path='.:/Applications/XAMPP/xamppfiles/lib/php') in Unknown on line 0

Я не уверен на 100%, что все это значит, поэтому я опубликую свой сценарий и был бы признателен, если бы кто-нибудь подробно рассказал мне, где я ошибаюсь, чтобы я мог понять и узнать, что я делаю неправильно в будущем ,

Заранее спасибо за любой вклад и помощь.
