# echo -e "[webserver]\n nginxClientMaxBodySize =\n" >> /usr/local/psa/admin/conf/panel.ini

Step 3: If you find that panel.ini is not present then create a sample file by giving the permissions to access it.

# cp /usr/local/psa/admin/conf/panel.ini.sample /usr/local/psa/admin/conf/panel.ini

# chmod 644 /usr/local/psa/admin/conf/panel.ini
