Anyone else suffering from this issue after doing an upgrade/update?
This may be in the category of bugs because it appeared to be working earlier today before upgrading Craft from the Free version to the Pro version I've been unable to save fields that are of type "Assets".
Current install is: Craft Pro 2.1.2564 Released on 7/15/2014
The issue is pretty straight forward. Attempting to save or edit a field that is set to the type "assets" fails.
Additionally, the sources available for assets on the create new field page incorrectly indicate that no sources are available. Error reads "No sources exist yet."
I did a run down where I verified the directory paths were properly set, and the permissions for those directories were also properly set. Both checked out okay.
Additionally, uploads to all my defined sources work as expected. This issue seems to only impact fields.
Result of trying to save or edit a field produces an error that appears saying "save failed". No further warnings show up.
Here's a shot of the available sources defined on my install, these were defined after my upgrade if that makes a difference.
