Reply To: support mail not found

As I have the same issue, I indeed see that WP-options for the entry “reservations_support_mail” is empty / blanc.
Perhaps it relates to an earlier installation of the easyRervations plug-in as you mention (I did deleted the free-version first as I had the impression that the Premium version was a stand-alone plug-in and only would conflict the free-version)
So, what (type of) value is expected for this entry?

Thx
