Unlocking an article or module that has been "checked out"
While an article is being created or edited in Joomla, it is given a locked status to avoid a second user logging in and modifying the same article at the same time. This is very important when there are multiple content editors managing a website but there may be times when the locked status is left on the articles, modules or items even though the user that it is locked to is no longer using or editing on the system.
In the Article Manager, articles of this status are denoted with a padlock icon next to the name of the module, article or item that they may have been editing.
However, there may be times you require access to edit a "locked/checked out" article.
In order to do this, you need to force a "Global Check in". Click on Tools and select Global Check in from the drop down menu.
Once clicked you will be presented with a results screen detailing how many locked and checked out items have been unlocked on the site.
