• Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\www\ihc.gov.pk\modules\mod_exmenu-j15\exmenu\exmenu.class.php on line 221

and there are a total of 27 of these.. what are these PHP warnings errors... or what what to do ?

This is because the PHP version you are using is 5.3 If you downgraded your PHP version to 5.2.x it will work perfectly If you're on a live server contact your hosting company If you're on local server and you are using WAMP you can download version 5.2.9 and install it then change the current active version to the new one.

i believe this is to do with PHP4's limited OOP capabilities and how you would have to pass values by reference manually (Foo(&$foo)); whereas in PHP5 this is done automatically.

If you're using PHP5, which is probably quite likely, you'll need to go through the code and remove any reference within it manually.
