title: CodeIgniter 500 Internal Server Error in subdomain
body: <p>I have a problem about 500 Internal Server Error. Here is the story</p>
  
  <ol>
  <li>I made a subdomain, and put my CI-based website there.</li>
  <li>I try to access it, and it works but there is some bug that need to be fixed.</li>
  <li>After I fixed the bug, I deleted all my files in my subdomain and reupload.</li>
  <li>I try to access it, but it showed 500 internal server error. I had checked the .htaccess file, nothing is wrong because I never changed it.</li>
  </ol>
  
  <p>here is my htaccess file</p>
  
  <pre><code>RewriteEngine on
  RewriteCond $1 !^(index\.php|assets|css|js|images|robots\.txt)
  RewriteRule ^(.*)$ /index.php/$1 [L]
  </code></pre>
  
  <p>here is my CI config file</p>
  
  <pre><code>$config['base_url'] = '';
  $config['index_page'] = '';
  </code></pre>
  
  <p>and when I checked on my cpanel error log when I try to access my site. it shows like this :</p>
