Everytime I tried to connect Constant Contact with WP Mail Optin I was getting the same error “The link you followed has expired” and I spent about 3 hours trying to solve it. Deactivating all the plugins allowed me to reconnect in a second, and then I switched all of my plugins back on and it works fine now. Thank you!
No, sadly I never did. I ended up having to completely redo the menu structure for the site, which was unfortunate.
Actually, I discovered the problem – conflict with another plugin: WP Popup Maker
