Impossible to add properties' values

Hello,
I just realized I am not able anymore to add values to a new or existing property.

When I add a value and then click Save, a white page is displayed and the value is not saved.

I attached a screenshot to show the value I added.

I recently upgraded Joomla to 3.3. Could this be an issue?

Thanks in advance for your help.

Your guessing is right.
There's an incompatibility between Custom Properties for J 3.x and Joomla 3.3.0.
We're almost through with the testing phase and we count on releasing the updated package soon (possibly tomorrow)

Just to pile on, I too, am having the same problem. Tags don't get saved when adding them. Looking forward to the fix!

Custom Properties 3.1.5, which is compatible with Joomla 3.3.x has been released in this very moment.

Great news! How does one get the latest version?
