What is an Open Operation on table WDC_Children_TEMP Error?
This error is probably caused when using a Ctree cache table, and the folder which you have asked Omni Security to use for the Ctree cache does not exist or does not have read/write access. Please use Option window to set the location for the Ctree cache files again. You can also check or edit the WDC_SQL_Local_Path setting in the DEX.INI file.
