The SHRINE qep did not find a query with the id requested for a particular user.
A SHRINE qep uses a database to store previous queries. The user asked for a query that doesn't exist in the database.
We suspect this error can only happen if part or all of the previous queries table in the QEP is deleted while a user is logged in. A bug in the SHRINE web client may cause the browser to lock up. Contact your QEP admin to determine if that is the case. Reload the web client in the browser to resume work.
If that is not the case, please report the summary, description, and all details to firstname.lastname@example.org so that we can investigate, help solve the problem, and provide better diagnostics in a future release.
