Joomla Component Installation XML File Can Create Error Regarding a Missing Administration Element

caroline — Sun, 18 Mar 2012 06:24:07 +0000

If a sub-folder XML file contains an “install” element, the Joomla installer might bypass the intended install xml file for the sub-folder variation. Only the top level installer xml file should have an “install” element. The core Joomla 1.5 Contact component has an administrator file (contact.xml) which contains the “install” element. I used the Contact componenent as the basis of a new component. The installation failed because the installer read the administrator/contact.xml as the installer xml file. The solution was to remove the and all header elements, and to add a top level element instead.

If your installation has this error, you might get this misleading message: “The XML file did not contain an administration element.” This is because the installer is not looking at the correct installation xml file. It’s not that the installation xml file doesn’t have an element, it’s that the sub-folder installation xml file is overriding the real installation XML file, and the sub-folder XML file does not have an administrator element.

Keep administrator and install in the top level XML file. Don’t use administrator or install in sub-folder configuration XML files.

To set event start and end dates back to “normal”:

UPDATE jos_eb_events
SET event_date = replace(event_date, ’19:00′, ’18:00′)
WHERE event_date LIKE ‘%19:00%’;

UPDATE jos_eb_events
SET event_end_date = replace(event_end_date, ’22:00′, ’21:00′)
WHERE event_end_date LIKE ‘%22:00%’;
