The cheatin uh? error

Moesia is great until you want to change template (or just have a look to compare with others) you get this message: cheatin uh?
Acooding to this:

It is a template error.
How can this be solved?
Thanks

I’m pretty sure it’s not a theme error:

  1. because nobody else reported it in over 100k downloads;
  2. I just checked and I can’t reproduce it;
  3. you’re referencing a topic about non-repo hosted themes which might not follow the best practices required to be hosted on wp.org.

I suggest you check your plugins, I highly doubt the theme is at fault here.

Pluggins checked, no problems.
Changed template to another one, no problems.
Re-installed the template, problems.
Never mind, I like the template so I will leave it as it is.
Best regards.
