Coding Style Compatibility introduced by
The method admin_page_load() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.

The expression $titles of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

6620
	 * all the files into one file.
6621
	 *
6622
	 * Pros:
6623
	 * - Uses only ONE css asset connection instead of 15
6624
	 * - Saves a minimum of 56k
6625
	 * - Reduces server load
6626
	 * - Reduces time to first painted byte
6627
	 *
6628
	 * Cons:
6629
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6630
	 *		should not cause any issues with themes.
6631
	 * - Plugins/themes dequeuing styles no longer do anything. See
6632
	 *		jetpack_implode_frontend_css filter for a workaround
6633
	 *
6634
	 * For some situations developers may wish to disable css imploding and
6635
	 * instead operate in legacy mode where each file loads seperately and
6636
	 * can be edited individually or dequeued. This can be accomplished with
