This is not a ChurchJobs.net or Paypal error. It is an error that your browser shows because it is being blocked from reaching Paypal.

We have only seen this error once, but it could be caused by your ISP or your antivirus software. Your ISP may have blocked Paypal for some reason. You might try rebooting your cable modem to see if that helps. If not, the only option is to us a computer on a different network.
