I attempted to uninstall a 3rd-party app (JBolo) in two different ways. First, directly from the ES Applications tab in the back-end. Second, after first uninstalling the related 3rd-party component from the Joomla back-end. Each time I received the following error when attempting to uninstall the app from the ES Applications tab:
"Sorry, but you are not allowed to delete a core application"
Can 3rd-party apps declare themselves as "Core"? What is the procedure for uninstalling a 3rd-party app when it is apparently identified as "Core"?
