500 using CodeIgniter

Question

I just moved the CodeIgniter project to a new server, and now I get a 500 error and do not output from the project. It works fine on my old server and in my test environment. I absolutely do not understand how to fix this problem, especially if nothing is used in the log files. Any help would be great!

Answer 1

Well, that’s awkward. I was missing php-mysql. CodeIgniter did not register the fact that he could not find it, nothing appeared in / var / log / messages. Installed it and suddenly, it works. Thank you all for your answers.

Answer 2

I get this problem on my real server with SuPHP. To avoid this, all PHP files must have 0644 permissions and 0755 directories.

To do this without a headache, do one of the following:

• Get an FTP client that will be downloaded using the permissions that you specify
• Find a PHP script that will change permissions based on filtering criteria after loading
• Get access to your host shell!

Answer 3

Some ideas for you:

• Are you sure there is nothing in the log files? Have you checked both the web server log files and the system logs (EG: / var / log / messages)? Have you checked all the logs included in php.ini?

• Double check the CI configuration settings. Perhaps you are pointing to the wrong database?

• You have confirmed that the underlying PHP script <?phpinfo(); ?> <?phpinfo(); ?> ? This would isolate the problem with CI.

Answer 4

Most likely, you did not specify the base url for the new location, you can install it from the file:

 /system/config/config.php 

in line:

 $config['base_url'] = 'your new url here'; 

Answer 5

Try downloading a new CodeIgniter project and trying to download a test environment? it works?

From my experiment, a 500 error is usually caused by a web server problem. But from what you said, you did not have .htaccess. Better just try downloading a clean CI project and see if your web server is OK or not.
