hello, the same thing is happening here, so as we have to wait for the theme update until next week, what do you recommend to restore the old version of woocomerce, or just leave the website running with the updated woocomerce,those Errors which they don't cause any problem so far.
Stop posting this stupid request all over the forum, grow a brain and go to the main Alidropship site at www.alidropship.com and fill in the Contact Us form ... you will also find support's email there too ... firstname.lastname@example.org
Just for future reference. This is a common thing with many Woocommerce themes when Woocommerce updates itself (not just DaVinci Woo) and they will be updated as soon as possible. You just need to have patience. Contacting the theme developer every time is unnecessary.
You can restore the old version from a backup but it is counter productive, I don't suggest it. At my end, it was only the tabs of the single product page. I restored tabs.php only. This is only if you updated this file in your theme as instructed by woocommerce plugin. But it is not necessary if your theme is updated.
