Today, We decide to discontinue support JV Cu3er 3D with free of charge because:
1. Due to the Cu3er license, We can't use it for our commercial template
2. All the issues (ex: permission issue...) are related to the Cu3er 3D core, not related to our works
But we still store JV Cu3er 3D in the free download section. You can download and use it on your website. If you have any issue please kindly find in the answered question in the JV Cu3er 3D forum.
If you still can't solve your issue then please kindly request a quote to get our support. You will be charged $50 for installation JV Cu3er 3D on your site.
Thank you so much for reading this!
