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.

6160
	 * This methods removes all of the registered css files on the frontend
6161
	 * from Jetpack in favor of using a single file. In effect "imploding"
6162
	 * all the files into one file.
6163
	 *
6164
	 * Pros:
6165
	 * - Uses only ONE css asset connection instead of 15
6166
	 * - Saves a minimum of 56k
6167
	 * - Reduces server load
6168
	 * - Reduces time to first painted byte
6169
	 *
6170
	 * Cons:
6171
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6172
	 *		should not cause any issues with themes.
6173
	 * - Plugins/themes dequeuing styles no longer do anything. See
6174
	 *		jetpack_implode_frontend_css filter for a workaround
6175
	 *
6176
	 * For some situations developers may wish to disable css imploding and
6177
	 * instead operate in legacy mode where each file loads seperately and
6178
	 * can be edited individually or dequeued. This can be accomplished with
6179
	 * the following line:
6180
	 *
6181
	 * add_filter( 'jetpack_implode_frontend_css', '__return_false' );
