I am getting two errors on two different sites...
"Sorry, there seems to be an error on the server. Please try again later." (www.arteatables.com)
"Subscribe to this blog - To manage your subscription options please login." (www.hatfieldmedia.com)
I have no idea why #1 is happening.
#2 makes no sense. I have never forced users to register/login to my site in order to join the mailing list. Why this sudden change?
Glad to troubleshoot just let me know what I can provide you.
