[SOLVED] When friendly URLs are enabled, my BO breaks

[sh0p]

Hello,

I have a problem with the Friendly URL. Whenever I enable the Friendly URL and generate the .htaccess file from the Back Office, the friendly url works in my website, but bugs the Back Office. I cannot access the Back Office when the Rewrite Engine on the .htaccess file is ON. But as long as I keep the Rewrite Engine OFF in the .htaccess file, and the Friendly URL enabled – my website gives me the following error:

'Error We're sorry, but the Web address you entered is no longer available'

I am using prestashop 1.3.1

How to make both the website and the BO work when Rewrite Engine is On in .htaccess file and Friendly URL enabled in BO?

Can someone help me out? Thanks in advance.

Regards.
