[+] infected item : /flatpress-1.3.1/fp-includes/core/core.config.php

if ($fullpath[0] != ‘/’)
trigger_error(‘config_read: syntax error. Path must begin with a /’);

[+] This line checks if the path starts with /. If it doesn’t, it triggers an error using trigger_error.
While this is valid, it might be better to use an InvalidArgumentException for more robust error handling.
