Hey there!
I'm trying to activate my kunena 5.2.8 with the JA moviemax theme.
I downloaded the theme from https://www.joomlart.com/member/downloads/joomlart/joomla-templates/ja-moviemax (version 7 Mar 2016 - 1.0.0.) and tried to install via Extensions / Manage / Install but get the following error messages:
Warning
JInstaller: :Install: Can't find XML setup file.
Error
Unable to detect manifest file.
I also tried to extract the files from the zip-file and upload to /components/com_kunena/template, but the theme isnt showing in Kunena Settings / Templates afterwards.
Best regards,
Marc
