Hi Md Fayeakuzzaman,
Thank you for your prompt reply and clear guidance.
At first I follow your suggestion to switching the theme to Twenty Twenty-Two, the issue of 404 couldn’t solve, I’m facing all pages showing error 404. Then I try to deactivate Dokan and only activate Woo-Commerce, all page look fine and error 404 was gone.
I realise when I change the Permalink structure at Post name to /%postname%/ and Product permalinks to custom base : /product/ , the error 404 display in all pages again. this happen with and without activate Dokan plugin. When I switch back to plain in Permalink structure then all work fine.
All page setting in Dokan are correct and all page are exist.
Hope this clue can give you some insight to solve the problem for me asap.
Thanks and regards,
eden
