WordPress › Support » Download failed.: Could not create Temporary file.
While the WrodPress system is Opensource and Platform Independent, many of the internal functionalities require a greater understanding of the Operating Systems they may reside on, the php settings that prevent/allow certain actions and last (definitely not the least) file/folder permissions on your Web server’s directories.
Windows and Unix based systems have a fundamental difference in how it handles the file permissions on a directory. Linux systems (derived from unix based) are pretty simple – Read Write and eXecute (rwx) permissions on the 3 basic groups – Owner, Group and Everyone. the 3 digits in the permissions – say 755 – means that System has rwx permission (7 – the first digit), Group and All have rx permissions (5 – Read/Execute).
Windows has always been a mess – a solid structure built with a rotten base. However, as most of us humans are infected by the Windows Gangrene, it’s useful to review the system of user permissions there.
If you are using a Plesk control panel (you will have different levels of access dependent on your Admin unless you are configuring a Dedicated Server), you have to go into the File Manager in Presk, click the ‘lock’ icon to get to the permissions – then click the Advanced button.
In windows (Plesk) there would be TWO entries – one for the Folder’s permission, one for the Files’ permission. There will also be multiple Users dependent on your IIS Server Settings. What you are looking for is the Internet User account – IIS_ or IUSR_ or similar. And don’t forget to ckeck the box for ‘apply to child objects’ check-box.
The Automatic Plugin Upgrades were problematic. un-checking the ‘php safe-mode on’ box to turn safe-mode off makes the ftp upgrade allowable.
