Hello, unfortunately I’m using a VPS in Arvixe and I bloquiei me to try to change the password of FTP.
  The firewall Arvixe has a rule that if I err password three times, I am unable to access FTP, Cpanel and etc. … BAD.

  Before being blocked, I noticed that this has only logging.

2015-07-17T02:56:41+00:00 ERR (3): Warning: Invalid argument supplied for foreach() in /home/vitor/public_html/loja/app/code/local/Sns/Ajaxcart/Block/Cart/Ajaxcart.php on line 36

And Cpanel error:
[Thu Jul 16 23:52:27 2015] [error] [client] client denied by server configuration: /home/vitor/public_html/loja/app/etc/local.xml

If this error is not related to the problem, please disregard this topic.
  I’ll end up signing another hosting, tired of Arvixe be so problematic with Magento.

  I always used the Magento Site5, I never had problems. In the Arvixe I have always problems.
