WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: What is “/wp-content/endurance-page-cache/”? Creating thousands of directories?, by Deb Shadovitz So here it is 1 year later and I am finding the same issues. Moving to another host, my provider wondered why I have so many files. I’m not sure this is the reason but I have an issue with caching happening when I don’t want and it cannot be turned off!. I looked and see that I also have this folder. My mu-plugins folder has a 3rd file called sso.php. Does anyone know what that one is? The 1st 2 are: endurance-page-cache.php endurance-browser-cache.php I am with JustHost. These all got bought by a $ machine and went to hell. I’ve tweeted and I will be calling in the moring. Reply To: What is “/wp-content/endurance-page-cache/”? Creating thousands of directories?
