Loading the nBill Stylesheet PDF Print E-mail
In some cases, you might see a warning appear when you try to run nBill's back end features, informing you that the stylesheet could not be loaded. NOTE: If this message appears straight after upgrading, before you take any further action, refresh your browser by pressing Ctrl-F5, or clear your browser's cache, as sometimes your browser can cache the old stylesheet.

Also Note: If an error occurs, and a page fails to load fully, this message may be displayed (because the error prevents nBill from getting as far as loading the stylesheet. In this case, the message can be ignored (but whatever error caused the problem would still need to be fixed).

Also Note: If you are using the default administrator template on Joomla 1.0.12 or above, or Joomla 1.5, or if the message only appears when you try to perform a certain task, you do NOT need to make any changes - the message will be due to an error that is preventing the page from loading fully (see above).

If refreshing the browser does not help, and the stylesheet message is always displayed when you access any page in nBill, then the component stylesheet failed to load. This can happen if you are using a custom admin template, or an old version of Mambo or Joomla. If you have this problem, make sure you are running the latest stable version of your CMS, or if you have a custom admin template, you will need to add some code to it to allow the stylesheet to be loaded.

To modify the admin template (only do this if you are not using the default administrator template), find the file named /administrator/templates/<name of template>/index.php, and open it in a text editor such as notepad (DO NOT use a word processor!). Immediately before the bit that says </head>, add the following code:

<?php
include_once( $mosConfig_absolute_path . '/editor/editor.php' );
initEditor();

// Workaround to include custom head tags from components
if (isset( $mainframe->_head['custom'] ))
{
    $head = array();
    foreach ($mainframe->_head['custom'] as $html) {
        $head[] = $html;
    }
    echo implode( "\n", $head ) . "\n";
}
?>

Please note: the above code is part of Joomla 1.0.12 and later. It is therefore released under the GPL, and is not part of nBill.
