Description:
------------


Suddenly 7 days ago:

1) Site with phpmanager script was very slow and took 4 minutes to go from page to page.

2) Other site gave the below errors:

 - Session_register not working with variables entered.

 - Warning: main(): Failed opening 'serex.php' for inclusion

and so on. I modified the php.ini using different options and paths, but no luck.  Before I started all that fixing in php.ini one site, after 3 days did fix suddenly and the script worked.  This was a login script.

 - script codes had to be changed from:

session_register('auth');

to
$_SESSION['auth'];

to work.

Now shopping cart script at still don't work.  I have deleted php and reinstalled it with cpanel 8, but still the smame.

Any help to this mistery?

Reproduce code:
---------------
Warning: main(rex.php): failed to open stream: No such file or directory in /home/bigtime/public_html/bigtime/includes/header.inc on line 28

Warning: main(): Failed opening 'rex.php' for inclusion (include_path='/usr/local/lib/php:/usr/lib/php') in /home/bigtime/public_html/bigtime/includes/header.inc on line 
28
echo 

Expected result:
----------------
Just the form as it is without the error code.

Actual result:
--------------
as above.
