Hello!
I set up your plugin (Feed by Mail), made all the settings, but after sending test letter I see an error in logs:
11-08-2014 14:09:13 – DEBUG – 47,1 MB – mail> Subject:
11-08-2014 14:09:13 – DEBUG – 47,1 MB – mail> Subject empty, skipped
But subject is not empty.
How can I fix this problem?
I tryed different ways of fixing it, but nothing has helped me.
SMTP was on and off, subject with tags or without — there was no difference.
Diagnostic tests were successful — I got two e-mails.
Wordpress 3.9.1, Feed by Mail plugin.
