Step 1. Log in to the server via SSH
Step 2. You can see your sites PHP information by putting an info.php
Create an info.php under your domain’s document root
vim info.php
<?php phpinfo(); ?>
Save the file.
Step 3. Set the permission for the info.php. For this, now call your domain.com/info.php you could see the PHP settings, then locate the domain’s php.ini location from the info.php
Eg: /opt/cpanel/ea-php56/root/etc/php.ini
It looks like the above-mentioned location.
In that php.ini enable the output_buffering
output_buffering = 1
Save the php.ini.
Step 4. Restart the httpd
service httpd restart
Now check the site after clearing your browser cache. It should be working fine.
