 * When I try to enable DB caching I get the following message:
 * > Database caching is not available. db.php is not installed. Either the C:\xampp\
   > htdocs\wordpress/wp-content directory is not write-able or you have another
   > caching plugin installed.
 * Where do I get the db.php?
 * And the test system is a windows directory, where PHP has write access – the 
   last sentence doesn’t make sense for me.

 * You can copy db.php from the wp-content/ directory inside the plugin’s directory
   itself.
 * In other to make sure that this doesn’t happen to other people I’d need your 
   help in troubleshooting the conditions that cause this error.

 * I had the plugin **DB Cache Reloaded** uninstalled _after_ I installed W3 Total.
 * The uninstallation handler of DB Cache Reloaded removed the db.php, and W3 Total
   didn’t reinstall it. 🙂

 * Would you mind doing a clean installation and let me know if the issue still 
   exists? Windows may need to have files written and not copied into place.

 * Thanks, I did the same thing, it seems when you disable DB Cache Reloaded it 
   takes db.php out, and then W3 is left without it. Thanks for the post!
