my theme breaks WP export

The basic idea for debug here is that theme apparently influences something it totally should not. Either something is done in a wrong way or in a wrong place.

  1. Check that theme is not running any functionality directly in functions.php.

  2. Check that all of theme’s functionality runs on appropriate hooks.

  3. For hooks that are used both on front-end and back-end conditionally exclude theme’s functionality that is not supposed to work on back-end.
