Hello,
After upgrading to latest on SMF 2.0.18, we get on each sent PM (they do still send):
https://BOARD/smf/index.php?action=pm;sa=send2
2: substr() expects parameter 1 to be string, array given
File: /home/USER/public_html/smf/Sources/Subs-Post.php
Line: 629
Line 629 is within // Newsletter Pro blocks:
if (substr($to, -4) == '.bad' || substr($to, -9) == '.complain')
return false;
This may need to be moved to after the array is defined for $to and then walk it, remove those entries and then if $to is empty, return false?
Anyway, hope you can fix it asap as its scrolling logs on each sent PM.
