# [Plugin: Hyper Cache] Caused Problems

 * I tried to install this and the first thing to consider is that the installation.
   When you went to settings and switched on the cached, it crashed with PHP errors
   since it was trying to write to a file in the direct parent file which didn’t
   exist nor had permission to access. I created this php file and set permissions
   to 666 to get over this. Looking at the contents of the file, it appeared to 
   be setting from WP Settings screen.
 * The main problem is that it was doing something weird which was causing the issues
   in the administration area of wordpress. For example, it was now impossible to
   delete a post without a server error. On the eventual removal of the plugin, 
   the post deleted without any issue.
 * On trying to un-install the plugin there were more errors generated by the plug
   ability script (apart of wordpress). I was unable to deactivate the plug, but
   trying for a second time deactivated it!!?
 * Its now un-installed and deleted.

 * WordPress cache plugins are different from normal plugins. They need to create
   a file “advanced-cache.php” in the “wp-content” directory. This script is “called”
   by php if found and if the WPCACHE constant is defined in wp-config.php.
 * If php cannot write a file there, yes, it’s a big problem. Another file with 
   some options is written every time the configuration parameters are saved. The
   file is called “hyper-cache-config.php” and saved in “wp-content”.
 * The working parameters have to be written in an file and not simply stored in
   the db, because when the cache is “called” no db connection is available.
 * May be the plugin use a wrong method to write such files. Many other users are
   using the plugin without those issues.
 * The plugin, still, create directories in “wp-content”, and files into those directories.
   If file system permissions stop such kind of operations, the cache cannot work.
 * May be I can add in the plugin some file system permission checks to avoid problems…
