Honestly I don't know about v1.39. I only started with Zen at v1.51 and have never needed to go any further back.

But otherwise yes, I have applied this fix to several stores v1.51 through to v1.55.

Thanks.
No, the configuration should be fine as stored in the DB. But as always if you try something >MAKE A BACKUP FIRST<.

Good luck.
