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

Question

Hi I am trying to make a members only website, I've trying to create a script with sessions etc however when I click my login button I get the following error:

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

I'm not 100% sure what this all means, so I'll post my script and would appreciate if somebody could tell me in depth where I'm going wrong so I can grasp and learn for the future what I'm doing wrong.

Thanks in advance for any input and help.

Answer 1

Set absolute path to prepend.php in .htaccess

Answer 2

My antivirus software likes to put the router.php in quarantine (effectively removing it from that directory). Check if yours did the same and if so restore it and create an exception for that file. Additionally you should configure your antivirus to notify you if it puts something in quarantine, so you can intervene in time.

Answer 3

This error come due to missing of server.php .Same happen with me. You check server.php file in your project directory.
