title: Codeigniter URL index.php twice
body: <p>Hi evrybody ‘im new to codeigniter and to MVC model as well,
  I need help to get my project working couse i’ve got this issues:</p>
  
  <p>1) i’m in the main page and i clik on the link of the “about” page, the css file does not seems to load.
    and even if i include the css in the head section the images are still missing in the page.</p>
  
  <p>2) in the configure file i’ve set the 
  $config[‘base_url’] = ‘’;
  $config[‘index_page’] = ‘index.php’;
  now if i’m in the about page and i clik again on the about link the link it’s missing becouse i set the link in the menu:
  About
  and so the index.php it’s loaded twice: localhost/mywebsite/index.php/index.php/about.
  i could set the condition to cut the link if i’m in the page i need but i would like to know if there is a more polite solution
  and hope that the solution it’s not to put my hands in to the mod_rewrite .</p>
  
  <p>I’ll like codeigniter because seems to be easy to configure and so really portable.
  and even if it’s simple i can’t figure out how to solve this issues </p>
  
  <p>Thank you everybody for your time!</p>
