With SMF 1.1 RC 1 and SMF 1.1 RC 2, when a member, who has the permission to send newsletters, try to open the page News and newsletters, he receive "An error has occured !".
I think at the line 94 in file Sources\ManageNews.php :
'mailing'
should be :
'mailingmembers'
Olright it fixes that bug ^^
tnx
Thanks for looking into a solution :) Will be fixed in the next release.
! An invalid default action was selected in 'News and newsletters' for users without the edit_news permission. (ManageNews.php)
