Getting error trying to download Valhalla Responsive theme in C5.8.5.5

I am getting the error message "Class ‘ZipArchive’ not found and this line in the top of the stack. “blindseason.net/concrete/src/Updater/Archive.php(60): Error->null”.
Thank you for your help.

If you have cPanel enable the zip extension in your php version.
zip-ext
, see attatched.

I had to manually download the zip archive and extract in my packages folder. Then in the admin interface I was able to install the theme.

And I have the zip extension enabled in PHP now from my cpanel.
thanks
