When attempting to use the SendPro Online software on a computer, a blank or white page is displayed.

• There may be an issue with your Internet connection.
• A firewall, anti-virus program, or proxy server on your network may be blocking the connection.

To resolve this issue:

1. Attempt to access any other website, such as www.google.com. If you also get a blank page at any other website, then there is most likely a problem with your internet connection. Contact your IT department or Internet Service Provider (ISP) for assistance.
2. If you do not get a blank page at any other website, but you continue to get a blank page in SendPro, then a firewall, anti-virus program, or proxy server on your network is most likely blocking your connection to the SendPro servers. To resolve this issue, you will need to whitelist or add an exception for the following addresses to ensure that traffic to and from them is allowed. Contact your IT department for assistance.
