A Fire Wall is set in place to stop attacks on the server. Sometimes if a lot of access is attempted to a site the Fire Wall may see it as an attack and lock out that IP address from accessing anything on the server. If this should happen to you then you should gain your IP address from: www.ip.liquidweb.com and Email me the returned IP number and asking me to check it. If blocked, I will unblock the address and white list it so it will not be blocked again.
