I recently upgraded from 4.0.4 to 4.0.6 and I am having an error with event discounts by date. As soon as I add a discount to an event, the registration page for that event gives this error:

Sorry. A non-recoverable error has occurred.
is not of type String

When I look at the civicrm_discount table, it has two entries with the same start date and end date for that event. I'm guessing that is the reason the code fails, but I don't know how to fix it.

Another side effect, is that after saving, upon returning to the event edit screen, there are two rows under discounts, with the same start and end date. Deleting the duplicate row doesn't work, unchecking the discounts box doesn't work either.

Hi Donald,
I cannot reproduce this on the demo server. I am suspecting this is related to the upgrade from 4.0.4 to 4.0.6. I have emptied the tables and tried to look at what could possibly cause this, but I can't figure it out. I'm not much of a programmer, clearly. 

What I did find is that it doesn't happen on the first time I add a discount, it happens once I edit the event. I.e. on a second save. For some reason, it seems to create a second, redundant entry. I have attached a screenshot, for a better idea of what happens in backend.

Can I do anything else to help with this?
