PHP Strict: WP_Customize_Filter_Setting::update() incompatible with parent method
|Reported by:||kurtpayne||Owned by:||nacin|
Full strict message:
Declaration of WP_Customize_Filter_Setting::update() should be compatible with that of WP_Customize_Setting::update()
This is happening because the declaration of WP_Customize_Filter_Setting::update doesn't accept a parameter.
On a different note, the original declaration of WP_Customize_Setting::update is protected. The visibility is changed to public, though, in WP_Customize_Filter_Setting, WP_Customize_Header_Image_Setting, and WP_Customize_Background_Image_Setting.
