Hi guys,

a new problem is occurring on our Joomla 1.7.3 / K2 2.5.4 site.

Everything has been functioning normally until today (the issue may have cropped up in the last couple of days, but today is the first time in a week or so we've made any changes.)

We've got several K2 items, but now when trying to assign a new main image to these items, after I click 'Save' the page goes completely blank and the change is not made.

I enabled debug mode and it looks like the following is the error :-

---
500 - **An error has occurred.**

DateTime::__construct() [datetime.--construct]: Failed to parse time string (**2011-11-17 13:11:32**) at position 0 (*): Unexpected character
---

Now, if I make a change to the item that DOESN'T involve changing the main image, everything works fine.

This is a very odd one. Has anyone got any ideas to resolve this?

Thanks for any help.
