For some reason the Shrine of Zenithar blessing isn't applying an effect to my character. When activated it plays the animation, displays the usual messages, but gives no sound effect and doesn't add the blessing of Zenithar. All other shrines work correctly. Anyone have an idea what's going on? I've checked it with TESEdit and it shows no mods affecting the shrine itself or the blessing...

Have you any mods ???

Have you crafted it alone in your homestead ???

The shrine of any particular location(s), all the Zenithar shrines not working ???

I figured it out. It was the Inferno Weapons and Armor Set mod: http://www.nexusmods.com/skyrim/mods/34764/?

Thanks TESEdit, turns out when I checked it previously, I had missed checking a reference in the blessing of Zenithar spell effect--which led me to the Inferno mod. Disabled the mod and everything works fine now.
