This seems to be a bug... but... there appears to be an easy fix.
Search subscriber.cgi for "sub message" and find the following line:
- Code: Select all
$message_template =~ s/\n//g;
Comment it out (add a # in front of it), or just delete the line. Then, repeat this in the subroutine named "edit" (search for "sub edit"), and try it again (this second step fixes it in the variable editing screen). This should get rid of that problem.
I'm currently questing myself as to why that line was there in the first place, and I can't think of any reason...
