Hello, Omar Khuram,
XStore is compatible with WPML (https://www.8theme.com/documentation/xstore/theme-translation/translation-with-wpml/), but any questions regarding the functionality of WPML should be directed to the support team of the plugin.
If you are unable to purchase WPML from here – https://wpml.org/purchase/, please contact their team to find an alternative solution. Unfortunately, we are unable to provide assistance with this.
Kind Regards,
8theme team
