出现服务器错误500

Question

I am getting an error 500, and when I check the logs on GoDaddy, it am getting below error:

PHP Fatal error: Class 'CI_DB_mysqli_result' not found in /home/rahmanhabib1/public_html/portal/system/database/DB_driver.php on line 706

and when I go to DB_Driver.php on line 706,

// Load and instantiate the result driver
$driver     = $this->load_rdriver();
$RES        = new $driver($this);

also the DB driver settings for my database are set to mysqli, and hosting with GoDaddy. Can't seem to find the issue as when I run it on local host, everything seems to be fine.

Check your apache error logs,try changing your .htaccess to

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>

OR

RewriteEngine on
RewriteCond $1 !^(index\.php|public|\.txt) 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1

Actually there is no any fault with DB_driver.php .

You may using Codeigniter V2. So in Codeigniter V2 they use database driver is MySQL . So if you use mysqli it will end up with this error.

If you want change MySQL to mysqli , follow method as below

1. In config/database.php

Change

$db['default']['dbdriver'] = 'mysql';

to

$db['default']['dbdriver'] = 'mysqli';

2. In system/database/DB_driver.php

Change

var $dbdriver       = 'mysql';

to

var $dbdriver       = 'mysqli';
