I have been trying to test one of my components in 2.5. It works OK in the sandbox but when uploaded to my server I get the following error:

Notice: Use of undefined constant __DIR__ - assumed '__DIR__' in

/httpdocs/j25/administrator/components/com_coursecalendar/helpers/loader.php on line 90

Warning: require_once(__DIR__/mvc.php) [function.require-once]: failed to open stream: No such file or directory in

The file mvc.php is there!

This is a problem with your server I think.

Try __DIR__ outside of your component.

__DIR__ only exists with PHP >= 5.3

Yes that will be it - thanks.
It is curently running 5,2.17 so I will upgrade it.
