In case that the above code on functions.php in the theme does not work, the other plugin or other setting may be wrong. Please deactivate other plugins and try to it.

Basically, the function for adding mime type is prepared by WordPress.
Reference: https://codex.www.ads-software.com/Plugin_API/Filter_Reference/upload_mimes

If “kmz = application/vnd.google-earth.kmz” in the end line of “List of allowed mime types and file extensions by WordPress” in “Mime Type Settings” was added and a kmz file cannot be updated to the Media, please add the following php code to functions.php in the theme.

add_filter('upload_mimes','add_custom_mime_types');
	function add_custom_mime_types($mimes){
		return array_merge($mimes,array (
			'kmz' => 'application/vnd.google-earth.kmz',
		));
	}

I downloaded dodekanes.kmz file and tried to upload to my WordPress (WordPress 4.4.2 and WordPress 4.5 RC2).
I can do it.

Please check the file extension seting in the plguin setting.

Isn’t a protected page hidden when the plugin is activated?
Please remove the cache and cookie of the browser, and please try it again.

I tested up WordPress 4.4 and 4.5 RC2 today.
When the plugin is activated, the password protected page will be hidden.

Please try to add the setting in this plugin setting.

ibooks = application/x-ibooks+zip

Ummm. I succeeded a kml/kmz file using your code.
Please check the file extension list in the plugin setting.

Yes, it supports.

You will add the following setting in the plugin setting menu.

psd = image/x-photoshop
ai = application/illustrator
eps = application/postscript
indd = application/x-indesign

Thank you for review!
For changing the style and words in the password pages, please see “https://codex.www.ads-software.com/Using_Password_Protection#Customize_the_Protected_Text” and add the code in fucntions.php.

I don’t check a multisite version, but basically the plugin can be worked because it’s very simple construction.

Firstly, please confirm the plugin in the simple mode.
And then, please check mime types.

ex. doc and docx
doc = application/msword
docx = application/vnd.openxmlformats-officedocument.wordprocessingml.document

Right

epub = application/epub+zip
mobi = application/x-mobipocket-ebook

Please try to change separate key ‘:’ to ‘=’.

Thanks!
Umm, it’s a strange…

Please tell me your environment.

WordPress version
PHP version

If you mistook the permission in the FAQ setting, please directly check the following DB data.

Default values : [wp_ds_faq_array] in “wp_options” table.
a:9:{s:31:”wp_dsfaq_plus_editor_permission”;s:7:”level_7″;s:30:”wp_dsfaq_plus_admin_permission”;s:7:”level_8″;s:35:”wp_dsfaq_plus_general_display_title”;i:0;s:28:”wp_dsfaq_plus_enable_ratings”;i:0;s:32:”wp_dsfaq_plus_disable_all_delete”;i:0;s:37:”wp_dsfaq_plus_disable_category_delete”;i:0;s:33:”wp_dsfaq_plus_disable_edit_delete”;i:0;s:38:”wp_dsfaq_plus_disable_frontedit_delete”;i:0;s:42:”wp_dsfaq_plus_apply_safetyoptions_to_admin”;i:0;}

Important permission is s:30:”wp_dsfaq_plus_admin_permission”;s:7:”level_8″;

What kind of a development environment do you use?

This plugin uses the following tables in the MySQL DB.

[Posted Data]
wp_dsfaq_name : category data
wp_dsfaq_quest: posted data

[Settings]
wp_options –> wp_ds_faq_array

Please try to use this plugin without the other plugins.
Or you install WordPress to the other directory and install this plugin.

Or please check the file size (.apk).
WordPress upload file size is decided by the PHP program setting.
You can see the “Maximum upload file size: ” in Media menu.

What kind of error does your WordPress?

About .apk file extension, I tested up WordPress 4.2.2 with PHP 5.3/5.6.
