Translation problem

HI

I use a the plugin for doing a weekly wrap up of all news of my site.

It works very well but there is a little bug in the email subject.

I use french translation and in the subject i have

[synapse2] Once Weekly Résumé hebdomadaire

The “once weekly” is not translated. “Résume hebdomadaire” is the translation for Digest Email.

I think the problem is in the class-s2-core.php at line 1554
$display = $scheds[$email_freq][‘display’];
There’s no transation __ for $display.
