 * I was able to install plugins using the “Add New” option. However, for the past
   three or four plugins that I’ve attempted to install I get the following fatal
   error:
 * > Fatal error: Cannot redeclare pclziputilpathreduction() (previously declared
   > in D:\Domains\domain.com\wwwroot\wp-content\plugins\wordpress-automatic-upgrade\
   > lib\pclzip.lib.php:5421) in D:\Domains\domain.com\wwwroot\wp-admin\includes\
   > class-pclzip.php on line 5498
 * How do I fix this error so that I can again use the “Add New” option?

 * Do you have the plugin WPAU (WordPress Automatic Upgrade) installed?
    If so, 
   remove it. It’s no longer needed as it’s now core.

 * Yes – I do.
    Will remove it.
