If my Use Web Server Rewrites = yes, pages return not found error. How can i solve this issue.
If you want enable from admin panel Web Server Rewrites = yes
Then make sure your .htaccess file in main root folder.
Yes, in my root folder consists .htaccess file, still, i get an error.
Make sure your Secure and Unsecure base urls should end with “/”.
Also check if mod_rewrite is enabled on your server.
For rest check this link Stackoverflow
Also, check if mod_rewrite is enabled on your server at all. You can create simple PHP script and execute it:
<?php phpinfo();
and search for mod_rewrite. If it's disabled, you'll have to add it according to the manual which you can find at http://magento.stackexchange.com/questions/21033/remove-index-php-from-the-magento-url-gives-404-err...
Another thing, if you're using Nginx instead of Apache2, then .htaccess won't have any effect. You'll have to configure Nginx properly, there are many manuals on the internet.
