Just after installing google analytics on my one of drupal site , my website become down . Having little knowledge of linux server , i could not figure out reason behind this.

Even try to take help of google , but could not find something useful.

But One thing i was quite sure that something wrong with permission imposed on htaccess file.

Today i logon to my linux server and changed all permission on folder html to 777. And site come live again.

If anyone face same problem during installing any module on drupad website , same hack can be used. But later set proper permission on said folder.
