Error in Installation version 1.3.1 WP-Super Cache

Hello!

I am trying to install WP Super cache 1.3.1 on http://www.railpnrstatus.in.

Domain & hosting are from different providers. Error is coming.

Warning! /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content/advanced-cache.php does not exist or cannot be updated.

1. If it already exists please delete the file first.
2. Make /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content writable using the chmod command through your ftp or server software. (chmod 777 /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content) and refresh this page. This is only a temporary measure and you’ll have to make it read only afterwards again. (Change 777 to 755 in the previous command)
3. Refresh this page to update /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content/advanced-cache.php
If that doesn’t work, make sure the file /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content/advanced-cache.php doesn’t exist:
1. Open /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content/plugins/wp-super-cache/advanced-cache.php$wp_cache_file in a text editor.
2. Change the text CACHEHOME to /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content/plugins/wp-super-cache/
3. Save the file and copy it to /webcorp1/www/corpusers/r/a/railpnrstatus.in/wp-content/advanced-cache.php and refresh this page.

Try to work both step but not able to resolve it…
