How can i fix 'php warning: post content-length' error?

This warning is usually thrown when the POST data size exceeds the value set in `post_max_size` in the `php.ini` file. Example:

// Large POST data being sent to the server.

Solution:

// Increase the post_max_size value in php.ini
post_max_size = 50M;

Remember to restart your server after making changes to php.ini.
