Strange thing has started occurring out of the blue. When I make a change to the pod (i.e. add a field) and click save, it spins and then confirms that the changes were made. But the new field isn't created. Same thing if I delete or edit fields.
Also, if I edit any of my advanced content types (i.e. change someone's name in one of the fields) and save the ACT, it doesn't save.
So I can't edit the Pods themselves or any of the ACTs created from those pods.
I also tried using the Pods User Role Editor and changes I made there didn't actually save when I saved.
I tried with regular wordpress pages and posts, and they save fine.
I have tried clearing the Pod Cache but it didn't help.
Here is my debug output: http://bit.ly/1fPUlSQ
