I'm using the latest version of wp-invoice. I've never had any trouble with it before, but now it's not updating after a client makes a payment.
I thought it might be a fluke, so I tried to record the payment manually using "Enter Payment" and when I tried to process they payment received the error "Could not save entry in invoice log."
I've never had any issues before, but I recently moved everything to a new server and this is the first invoice I've done since I moved. I have no other issues related to the server move so I would be surprised if something cropped up with this.
I've double-checked all my settings and everything relevant is there, including the IPN url. Any thoughts or ideas about how to start trouble shooting this?
