Hello,

I am using the opt-in Acymailing add-on of SPBuilder (bottom of this page: https://uottawa.saea-tlss.ca/en/virtual-campus). When someone subscribe to my newsletter, he or she got an error message (see attached). However, the subscriber still receive the confirmation email and is subcribed. However, it mislead the user about what is happening.

I am using the very last version of safari on a MacBook Pro.

Do you have any clue why it's doing that and how to solve the issue?

Thank you,
