[Forums] Unique constraint violation when running on 9.1 and Oracle database

Hi,

After installing WikiSystems in our development environment and opening the application I see an "Internal error has occurred and was logged" error message in the browser.

This is running on 9.1.0.20 with an Oracle database.

See below for the error logs from ServiceCenter. Any clues on how to fix this?

ORA-00001: unique constraint (OSADMIN_DEV1.OSIDX_OSUSR_CRX_PAGE1_5TITLE) violated
