If you are not using Enterprise version location of the files may be different

You may have been prompted in admin panel to upgrade to the latest version. To do so:

1. SSH to your HostBill Enterprise server as root:

# ssh root@yourhostbilladdress

2. Download & unzip latest ioncube loaders:

cd /root
mkdir tmp
cd /root/tmp
wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.zip -O ioncube.zip
unzip -o ioncube.zip

3. Overwrite old ioncube loader files:

/bin/cp -rf /root/tmp/ioncube/* /usr/lib64/php/modules/
chmod +x /usr/lib64/php/modules/ioncube_*

3. Restart webserver & php-fpm:

service nginx restart && service php-fpm restart
