A while ago in this thread here:
https://forum.virtuemart.net/index.php?topic=126403.0
GJC Web Design described the way to get rid of "Virtuemart aio" empty menu item in Joomla's "Components" menu by doing this in the database:
SELECT * FROM `jos_menu` WHERE `link` LIKE '%allinone%'
Now my question is... what SQL query is necessary to remove "tcpdf" empty entry from Joomla's "Components" menu?
