Firstly go and login to your SSH, then use the following command: nano /usr/local/lib/php.ini - Activate the and find the feature by pressing crtl+W and then entering desired setting, the interface will scroll to that setting. In mine case, I've searched for post_max_size. The setting to your desired configuration then changed the post_max_size setting to 16M. Alter the setting to your desired configuration. You can changed the post_max_size setting to 16M, exit the editior and the SSH.
