Mysterious problem. Shortcodes work in pages e.g. google map is integrated, but not in posts. Same problem with every kind of shordcode. What has happened?
I am using atahualpa 3.7.3, WP 3.31. I imported atahualpa settings from earlier installation working with WP 3.21 and atahualpa 3.7.3.
What to do?

What happens if you try it with twenty-eleven?

It works best.
In the meantime I totally reset ata configuration and built a new one.
I also reconstructed my custom widgets. Now it works perfect as ever.
