I just migrated my site and after it propagated I went to the backend to make updates and am now receiving an error of the supplied nonce is invalid. Has anyone ever dealt with this? This is throughout the whole site now where I can’t change anything. Please help. If the whole site is broken how do I fix it?
Nonce issue isn’t related with Talon theme, I am afraid. To confirm, you can test it by switching temporarily to one of default WordPress themes.
