Running Joomla 5. Downloaded and tried to install Waggy Tails template for Joomla 5. I receive the error message: “JInstaller: can’t find xml setup file. Unable lto detect manifest file”.The download says Waggy Tails is for Joomla5 but I wonder if it is for joomla 4. Thank you for the help!
You should have instructions on how to use the quickinstall from the author. You can contact them for support as @ki-themes has advised you.
