Hello,
These errors https://prnt.sc/rvq3ea https://prnt.sc/rvq1he appeared because you disabled XStore core plugin. This plugin is required for our theme. Why did you disable it?
Log in to your Cloudflare account http://prntscr.com/rw2yu7 to allow us to clear CDN cache after the update because we faced issues because of this previous time.
