PHP版本从5.3更改为5.4（5.5）后，.htaccess规则无效

Question

当我将PHP版本从5.3更改为5.4或5.5时，.htaccess文件中的规则无效。

哪些规则不兼容？我很高兴有任何意见，谢谢！

--- htaccess的：

Options +FollowSymlinks
DirectoryIndex index.php
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{REQUEST_URI} !/(assets/|404/|png/|js/|jpg|clearfavour)(.*)$
RewriteCond %{SCRIPT_FILENAME} !/(assets/|404/|server/)(.*)$
RewriteRule ^(.*)$ /index.php?params=$1 [L,QSA]
RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
