Hi again,
Thanks for your feedback.
First, if you have customization files or languages you should back up them. In the other hand, you can use the Child Theme to write them because they will be lost when updating our theme.
Second, we also got access to your website then checked the update notification. However, your server doesn't receive our update notification. In this case, you should update our theme manually.
- Step 1: Download the newest version from ThemeForest market.
- Step 2: Upload it via WordPress or FTP account.
Please check, then feedback us.
Best Regards,
NooTheme
