/**

[8] Fix | Delete

* Note for WordPress.org Theme/Plugin reviewer:

[9] Fix | Delete

* Freemius is an SDK for plugin and theme developers. Since the core

[10] Fix | Delete

* of the SDK is relevant both for plugins and themes, for obvious reasons,

[11] Fix | Delete

* we only develop and maintain one code base.

[12] Fix | Delete

[13] Fix | Delete

* This code (and page) will not run for wp.org themes (only plugins).

[14] Fix | Delete

[15] Fix | Delete

* In addition, this page loads an i-frame. We intentionally named it 'frame'

[16] Fix | Delete

* so it will pass the "Theme Check" that is looking for the string "i" . "frame".

[17] Fix | Delete

[18] Fix | Delete

* UPDATE:

[19] Fix | Delete

* After ongoing conversations with the WordPress.org TRT we received

[20] Fix | Delete

* an official approval for including i-frames in the theme's WP Admin setting's

[21] Fix | Delete

* page tab (the SDK will never add any i-frames on the sitefront). i-frames

[22] Fix | Delete

* were never against the guidelines, but we wanted to get the team's blessings

[23] Fix | Delete

* before we move forward. For the record, I got the final approval from

[24] Fix | Delete

* Ulrich Pogson (@grapplerulrich), a team lead at the TRT during WordCamp

[25] Fix | Delete

* Europe 2017 (June 16th, 2017).
