So the error I am having is that I keep getting an error like
Warning: include(/public_html/core/inc/inc/user.inc.php) [function.include]: failed to open stream: No such file or directory in /public_html/core/inc/init.inc.php on line 23
Warning: include() [function.include]: Failed opening '/public_html/core/inc/inc/user.inc.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /public_html/core/inc/init.inc.php on line 23
Here is my files.
init.inc.php
All it is, is an include that allows me to connect easier than writing it out every time. Everything I have tried has NOT worked.
protected.hp
