This can be frustrating when you are new to wordpres and/or woocommerce. You just created your first product, and got 404 when trying to see it. Fortunately solution is quite simple. In backend panel go to “Settings”, then “Permalinks”. In “Common settings” section make sure “Post Name” is selected, if not, choose it – it will look like “http://newbl.blastar.biz/sample-post/”. Then look below, in “Product permalink base” section choose “Shop base” – it will look like “http://newbl.blastar.biz/shop/sample-product/”. Click “Save CHanges” and below you should see new box with .htaccess settings like:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Just copy it and paste to your .htaccess. All links should work now!
