The problem seems to be intermittent as it does not happen consistently. Looking at plug-ins in general, there seems to be issues with caching plug-ins as they all seem to address the issue. They all indicate to reduce the cache time to less than the nonce time. I have set my cache time to 10 hours as I read that nonce is either set by default to 12 or 24 hours….
Today, had user get “Invalid nonce, please refresh your screen and try again” five times before the form was accepted 🙁
