Indications:

  • Service log states "Error in filter update at step 4, invalid use of null".

Cause:

  • Error is caused by a null entry being included in the filter.

Solution:

  • Stop the Chaperon service.
  • Click Tools > Server Tools > Download Filter Database...
  • Select Yes to download the full filter.
  • Once the download is complete, start the Chaperon service.
