not working modules

Hi,

by any chance does anyone know why my site is working but half of the modules don't work.

sample: I click on the account button and it does work, but then the profile button it gives me an error page, please let me know if you've been having the same problems and how to get it fix, thank you in advance.

 Mod_rewrite isn't installed on your server or isn't working correctly.. If you turn off friendly links in admin and everything works then that's probably the problem.

You can also check if you have uploaded the .htaccess file in the root directory of your Dolphin. This file contains all the rewrite rules for the site to work normally.
