 * after update could not detect correctly, some method to finish install, this 
   think block with detection of right chmod for wp-content directory, the error
   reporting by W3 total cache is please make sure wp-content are in 755 because
   it in chmod detected is 755

 * Same here – I cannot complete the update because the plugin says it cannot write
   to config files and wp-content directory although the permissions should allow
   it and did so for the previous versions.
 * Also detects permissions incorrectly – like: says the current permissions are
   755 and they should be changed back to 755.
 * Also:
    “Either the /(MY PATH)/httpdocs/wp-content directory is not write-able
   or another caching plugin is installed.This error message will automatically 
   disappear once the change is successfully made.” the directory is writeable, 
   previous versions worked fine, and there are no other cache plugins
 * I even removed the previous install and did a clean install of W3 Total cache…
   but with no success.

 * This issue should be fixed in the latest version. Please try it and if it works
   mark thread as resolved.
