Creates an error page for index.html

After much testing I have identified that Cache Enabler is creating a web page called index.html with the following error on it, see below:

Fatal error: Uncaught Error: Call to undefined function wp_die() in /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-content/advanced-cache.php:167 Stack trace: #0 /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-content/advanced-cache.php(9): _ce_file_path() #1 /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-settings.php(84): include('/srv/users/serv...') #2 /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-config.php(40): require_once('/srv/users/serv...') #3 /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-load.php(37): require_once('/srv/users/serv...') #4 /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-blog-header.php(13): require_once('/srv/users/serv...') #5 /srv/users/serverpilot/apps/main-site-duckonwater/public/index.php(17): require('/srv/users/serv...') #6 {main} thrown in /srv/users/serverpilot/apps/main-site-duckonwater/public/wp-content/advanced-cache.php on line 167

The only way to resolve is to remove the plugin. The site now redirects /index.html to the home address as it should.

Has anyone else experienced this? I only discovered this when index.html started to come up in Google searches! Maybe worth checking your websites.

Hope there is a fix soon as this is by far the best cache plugin about for WP!
