I've an interesting problem (if you want to use that word). I've a user that tried to access the Tasks.aspx page, and upon entry the grid responds with red error text saying "An error has occurred", and then the page finishes rendering. A side effect of this is that all the actions in the ribbon are disabled.
What seems to be the issue is that a filter was created, with start and end dates, and there is an error in the filter (something along the lines of 'start date cannot be after end date'). How this got in this state really isn't the problem, I just want to get rid of the filter for that user.
Normally you'd go into the ribbon, and select "No Filter". However, as the actions are all disabled in the ribbon, this person cannot clear it out.
Is there a way to, via either PowerShell, or via entry into the underlying database tables, remove this person's filter? This issue right now basically prevents them from doing anything in the Tasks.aspx page.
Thanks! - M
