Hi there,
I am having the same problems. I am on WP3.2.0 with subscribe2 version 6.5
I post twice a day to my blog and send out a daily email update.
Yesterday, the system sent out 1 email update which is perfect. Today it sent out 4 duplicate emails. A few days ago it sent out 2 duplicate emails. It is very random as to when it sends duplicates.
The update above from Matty Rob with making changes to the .php file, will this work for me in this scenario?
I really appreciate any help as I am starting to pee off my subs with duplicate emails.
Thanks
Ryan
