Products affected: SendPro® Online software for Windows or Mac

Issue

When attempting to use the SendPro Online software on a Windows or Mac computer, a blank or white page appears.

Cause

  • 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.
  • There may be an issue with rendering web graphics in the program.

Resolution

Solution 1: Refresh the program

  1. Click the Refresh button at the top of the SendPro Online software window.

If you get a white page after clicking Refresh, see Solution 2.

If refreshing solves the issue, but it has to be done every time the SendPro Online software is launched, clear the SendPro Online software cache. See Clearing the cache in the SendPro Online software.

Solution 2: If you get a white page after clicking Refresh

At the bottom left of the SendPro Online software window, note which of the following appears:

If it says "about:blank" at the bottom of the SendPro window:

  1. Try to visit any other website, such as www.google.com. If you also get a blank page at other websites, 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 other websites, but you continue to get a blank page in the SendPro Online software, then a firewall, anti-virus program, or proxy server on your network is most likely blocking your connection to the SendPro servers. To solve 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.
