If the Joomla Wrapper Module
or Component does not have a page to load an error will result.
If the Wrapper is published without a target URL entered in the Wrapper parameters a Javascript alert will pop up in FireFox saying
"The URL is not valid and cannot be loaded"
In IE 7 the page will be prevented from loading.
The solution is to enter a target url for the Wrapper to load.
For Wrapper Module enter the target URL in the module settings.
For Wrapper Component enter the URL in the settings of the menu item that links to the Wrapper Component.
Also note that the wrapper uses Itemid=
Link to wrapper item:
index.php?option=com_wrapper&view=wrapper&Itemid=89
