 Hi.
 I'm Genki Taniguchi working on SAKURA Internet Inc.

 We have a plugin for our hosting service customer.
 https://ja.wordpress.org/plugins/sakura-rs-wp-ssl/
 AOSSL plugin.

 Activate and When the plugin's button clicked, writing some script to
 htaccess.
 And when the plugin deactivated, delete which script.
 Problem is this delete function is not work on 4.9.0.
 (Writing is working)

 On 4.8.3 it worked correctly.My environment is below.
 Apache 2.4 PHP 5.6, 7.1 MySQL5.5
 Wordpress 4.9.0
 htaccess's permission is correct.(664)

 Best regard.
