The directory tmp does not exist and could not be created I keep getting this error since updating to Drupal 7.5.8 and cannot get rid of it regardless of trying all I know. Even adding it / copying-pasting the previous tmp dir or changing the tmp file name (eg tmp3) doesn't solve it.  Any files placed in the directory are writable unless I need to add a new Drupal 'group' in security.

Any one know how to solve this update issue?
You didn't mention the actual (complete) value for the path of the "Temporary directory" you want to use. But something that should work, pretty sure, is like so:


Navigate (in your web browser) to relative path admin/config/media/file-system.
Copy the value you have entered for "Public file system path", assume it's some/path/files.
Paste the copied value (like some/path/files) in the field "Temporary directory", and append to that value something like /temp, so that it becomes something like  some/path/files/temp/
Hit the Save configuration button and you should be good to go (Drupal will, automagically, take care of the rest).
