Cacti导入模板报错 Error: XML: Hash version does not exist.
将新版本到处的cacti模板导入到旧版本的时候，就会报Error: XML: Hash version does not exist.，
解决的办法是修改xml里面的相关hash值。
以下是cacti xml hash的一些说明：
Take the following example: <hash_040018258d1c9487a6c58dd804f4a012007664>
The first 2 digits are the type of the template.
The next 4 digits are the Cacti version it was created on.
The next 32 digits are a random number.

查找相应的xml文件中关键字“0018”，根据自己的环境找到对应版本替换即可，以下是最新cacti hash版本表

$hash_version_codes = array(

"0.8.4" => "0000",

"0.8.5" => "0001",

需要导入新版cacti模板的时候，只需要修改hash里面的version相关字段即可，记住是全部修改，可以用记事本查找替换，一般都有上百处替换。
