Hotspots Docs
Updating manually
As noted in the installation section, installing and updating Hotspots is actually the same thing. If the automatic update using Joomla!'s extensions update feature does not work, please install the update manually following the instructions in the installation section of this documentation.
When installing an update manually you MUST NOT uninstall your existing version of Hotspots. Uninstalling Hotspots will remove ALL your settings. You definitely not want that to happen!
