Seems like 1.3.7 is not installed on this website, so we cannot see the error.
I had to downgrade it to an older version because the new version didn’t work. But please recheck it now.
Seems like it still have the old version of the plugin.
Do you have a cache system on your server or site? purge the cache
Did you customize the templates on your theme? if so, remove the wpsc folder of your theme
Wpsc folder was removed, and the cache was purged, still doesn’t work. Installed plugin version 1.3.7
Hi,
We just updated the plugin to version 1.3.8.
Updating the plugin to the latest version, and clearing the cache should solve the issue
After the plugin update V 1.3.8, everything works fine. Thanks for the help 🙂
