Hello Kristen,
Thanks for using our plugins and welcome to the forums!
I’m sorry you are having this issue. I’ll try to help you get this sorted.
I will need some further details from you as I don’t have the Smart Offers plugin.
1. On which pages do you get that error message?
2. What is actually happening / not happening due to that error?
3. Can you confirm that the error goes away when you disable only Smart Offers and leave the calendar plugin active?
4. Can you confirm that the error goes away when you disable the calendar plugins and leave Smart Offers active?
Thanks in advance!
Cheers,
Andras
