    Hi Will, this was a typo bug. Thanks for reporting this! I have published new version of the plugin (1.1) with the fix. Try it out and let me know if you still see any problems.

    I’ve installed the plugin on WP 3.4.2, PHP 5.3 and MySQL 5.1 but when I was activating the plug-in I am getting this message:
    “Fatal error: Cannot redeclare wincache_get_cache() (previously declared in C:\Inetpub\wwwroot\swedcham\wp-content\object-cache.php:29) in C:\Inetpub\wwwroot\swedcham\wp-content\plugins\wincache-object-cache-backend\object-cache.php on line 31″

    Any ideea what can be wrong? Thank you!
