# “Upgrade automatically” generates errors, not functioning

 *  Resolved [rklau](https://wordpress.org/support/users/rklau/)

 * [18 years, 2 months ago](https://wordpress.org/support/topic/upgrade-automatically-not-generates-errors-not-functioning/)
 * Have 2.5 installed and working properly at [http://www.rklau.com/tins/](http://www.rklau.com/tins/).
   Only feature not working is the plugin updater. When plugins are activated, I
   get the following error when I try and “upgrade automatically” for any plugin:
 * ‘Fatal error: Cannot redeclare pclziputilpathreduction() (previously declared
   in /xxxx/yyyyyyy/public_html/tins/wp-content/plugins/wordpress-automatic-upgrade/
   lib/pclzip.lib.php:5421) in /xxxx/yyyyyyy/public_html/tins/wp-admin/includes/
   class-pclzip.php on line 5489’
 * When I deactivate all plugins, I get a different error:
 * ‘Unpacking the update
 * Could not create directory’
 * I’m happy to deactivate all plugins (I’ve read elsewhere this is required for
   the upgrade to work), but it would appear that I need to change permissions on
   a directory somewhere. Any ideas?
 * –Rick

 * Once you upgrade to the latest WordPress Automatic Upgrade plugin the upgrade
   will work without having to disable it. (I think 1.0 fixes it)
 * As for the Cannot create directory error, That sounds like a permission error.
   
   Can you check that the folder wp-content/upgrade/ exists? If not, try creating
   it and running an update again. Allthough the folder should be autoamtically 
   created, it may not be being created correctly.

 * As dd32 hinted at…the “Cannot create directory” error is indeed a permissions
   error. Make sure your wp-content/plugins and all the sub-folders in the /plugins
   directory are writable and it should solve that issue.

 * Great feedback everyone, thanks!
 * I had to create the /wp-content/upgrade directory (it was not present), set permissions
   to 777, then update the permissions in wp-content/plugins to 777 as well. Finally,
   I emptied /wp-content/cache – and plugins are now updating successfully.
 * Thanks for the help.

 * If this is related to WPAU or WordPress Automatic Upgrade plugin conflicting 
   with the automatic upgrade function of the WP core, you can disable WPAU and 
   try upgrading again:
