Enabling Legacy Support in Joomla 1.5
From HwdMediaShare Documentation
The future of Joomla is Joomla 1.5, it has a new framework with code based for the Joomla! core completely re-written and built with PHP5. Thus, a lot of existing extensions, plugins, templates and modules for Joomla! version 1.0.x does not work or fail to work properly in the Joomla 1.5, sometimes not even able to upload and install the package. Users will get error messages such as Direct Access to this location is not allowed and Must Enable Legacy Mode In Global Config To Complete This Task. Joomla developers are kind enough to provide a legacy mode in Joomla 1.5 that supports compatibility with extensions designed and developed for older versions of Joomla.
To enable and switch on legacy mode in Joomla 1.5 simply follow the steps below to publish the Legacy Mode plug-in.
- Login to your Joomla 1.5 Site Administrator panel (http://www.domain.com/administrator).
- Move your Mouse over Extensions in the main horizontal menu, then click on Plugin Manager.
- In the Joomla Plugin Manager, locate the plugin named System - Legacy, and then click on the check box in front of it.
- Click on Enable button.
- Ensure that Legacy: 1.0 status appears on the top right corner of the administrator page, and the Enabled column for 'System - Legacy' is ticked.
- The Legacy Mode has been enabled.
