# Hyper Cache – Empty Cache Directory

 * I’m testing out Hyper Cache because it sounds like a great plugin, but I’m having
   some trouble getting it up and running. The plugin was able to create a /hyper-
   cache/ subdirectory of /wp-content/cache/, but when I looked inside there were
   no files. After page visits, I checked the source code to see if there was a 
   comment indicating the page had been served from cash, but there was none. However,
   I did find this script before the closing body and html tags:
 * `<script>function lc_get_cookie(name) {var c = document.cookie;if (c.indexOf(
   name) != -1) {var x = c.indexOf(name)+name.length+1;var y = c.indexOf(";",x);
   if (y < 0) y = c.length;return decodeURIComponent(c.substring(x,y));} else return"";}
   if ((d = document.getElementById("commentform")) != null) { e = d.elements;var
   z = lc_get_cookie("comment_author_email_c4c97828dcdab6723a7c27e7c99b35d5");if(
   z != "") e["email"].value = z;z = lc_get_cookie("comment_author_c4c97828dcdab6723a7c27e7c99b35d5");
   if (z != "") e["author"].value = z.replace(/\+/g, " ");z = lc_get_cookie("comment_author_url_c4c97828dcdab6723a7c27e7c99b35d5");
   if (z != "") e["url"].value = z;}</script>`
 * My guess is it looks like the plugin’s code to fill in comment forms on users
   served a cached page and that the plugin is working in a limited capacity.
 * I don’t know if its related, but I ran into an issue an the absent constant define(“
   WP_CACHE”, true); after the WPLANG part (which isn’t there), I just stuck it 
   in at the top where WP Super Cache defines a similar constant. I also ran into
   some file not found errors, but the text was obscured by the WordPress Admin 
   sidebar. These errors disappeared after I saved the settings.

 * Hi did you clear the cache after you entered the following **define(“WP_CACHE”,
   true);** in the wp-config.php file?
 * Then did you open up a page or post in the browser and then did you check the
   cache folder again? You can also click on **Compute the cache size** button.

 * I took your advice and 1) pressed “Clean the whole cache” under the Hyper Cache
   settings page; 2) Browsed pages and posts when not logged in; then 3) pressed“
   Compute the cache size” under the Hyper Cache settings page.
 * When I compute the size, I get a label with no value, just “Cache size:”. Cache
   directory is still empty. Hope that helps.

 * Try the following, deactivate all your other plugins except this one and carry
   out another test. You can try also the FAQ in the following [link](http://www.satollo.net/plugins/hyper-cache).
