upgrade magento from 1.9.0.1 to 1.9.2.2 url's problems

[nico94]

hello Today I updated my Magento 1.9.0.1 to version 1.9.2.2
inside the Wizard Installation I entered the old database of my shop .
just I entered the frontend I noticed that all of the links do not work (the browser shows me the error 403 ) , same thing for the backend.

I saw that the url to work must contain /index.php/ , which was not the case in my old shop .
wondering if it were possible to remove index.php from the URL ( I 've tried to edit the .htaccess file but it did not work ) .
thanks in advance for your help
best regards .

To remove index.php, go to System > Configuration > Web > Search Engine Optimization and set Use Web Server Rewrites to YES.

Hope it will help you, else let me know again.
