I have a new site with a page that has a conversation block on it, going out to about 140 people. when i post the message, the page freezes up and i get "an unexpected error occurred". The post does go out however, while the page is frozen, i guess waiting to deliver to the subscribers? but i can't exit the page until it seems it has gone through a sending process? The browser wheel just spins and spins. I cant even log out. There were some email failure messages I got back in my mail box. In case that was some issue, I Deactivated those user accounts, but when trying a second post, the same deactivated users accounts still caused an email failure message to my mailbox., frozen page, etc. any solutions would be really appreciated. thank you
