i have 3 issues…
- i have an error that the product details in the admin panel doesn’t open and it gets error 404.
- on the frontend it, when i navigate to any link it doesn’t navigate but it only change the URL but keep the page on the homepage.
- about the theme, i use unitheme2 older version but it doesn’t work now.
