I'm running the latest version of EE (v5) but when trying to login to the control panel, I keep getting a form expired message - "Error: This form has expired. Please refresh and try again."
This is happening on all computers and all browsers apart from my work computer. That's the only one I can still login on.
Any ideas on how to solve this issue would be hugely appreciated as we're putting this website live in a week's time! Cheers in advance!
