I couldn't find any Thread that handles this problem, so I hope someone can help me.
I wanted to insert new order statuses. So I created the new ones and the old ones (that have been there from the start) seemed to not fit in my scheme anymore, so I deleted them. Then I changed the order of the statuses. Everything worked out well.
But now, when I'm testing to buy something, I cannot change the order status anymore. By changing the status the following message appears: "WARNING: An Error occurred, please refresh the page and try again."
Can anyone tell me why this error occures and how I get rid of it?
Thanks in advance!
