For example, on my new Dracthyr character I was getting the error trying to copy or save a new HUD from what i used on my priest. However, the HUD on my new character had a bunch of things turned off. Extra action bars and such, for example. When i enabled all that was originally missing from the Priest’s HUD, I was suddenly able to save/copy and generally make a new HUD for my new Dracthyr as desired.
Maybe this will help you guys?

That just worked for me.

1. Went to another character
2. Enabled all action bars
3. Copied my custom profile
4. Went back to my main character
5. Selected the copied profile
6. Made desired changes
7. Changes now will save

Still there must be a bug… a couple days ago my profile completely disappeared. Now I couldn’t save changes without a work around…

A combination of the two methods worked for me. Delete the specified files from all toons and then turned on party and boss and raid frames in edit mode. Boom, can save and create templates without error. Thanks!

good god i was going through my addons and thinking it was an addon or a weakaura, then at one stage i said fine ill turn you all off…lua error.
the copy/delete worked, but it naturally errors right after.

Some good info in this thread, but MAN-- idk… This a really basic error that should have been caught before it was allowed to go live.
