Thank you for using XStore. We have checked it in depth. Take a look please: https://prnt.sc/1vqtgbq
Don’t you use our theme for these projects anymore?
Because you can use 1 license for 1 project (dev and production sites) according to ThemeForest license policy https://themeforest.net/licenses/standard
One standard license is valid only for 1 project. Running multiple projects on a single license is a copyright violation.
