Hi Paul,

Can you send us the stardog.log file from the Stardog home directory?

Thanks,
Pavel

Hi Paul, thanks for the report. This is a bug with the interaction between the webconsole and the 5.x HTTP server. It will be fixed in the next release. Until then, I would recommend using the CLI or one of the various APIs for executing your query.
