JFolder::create: Could not create directory

Check to see if your path settings are correct in Global Configuration settings and that the folder is writable 755.

If you recently moved the site from a sub-folder or another webhost the path settings will have changed.  It's quite easy to overlook this step.   public $log_path = '/home1/YOURSITE/public_html/logs'; public $tmp_path = '/home1/YOURSITE/public_html/tmp';

In this case we needed to change home1 to home

public $log_path = '/home/YOURSITE/public_html/logs'; public $tmp_path = '/home/YOURSITE/public_html/tmp';

OR

public $log_path = '/home/YOURSITE/public_html/SUBFOLDER/logs'; public $tmp_path = '/home/YOURSITE/public_html/SUBFOLDER/tmp';

In this case we needed to remove SUBFOLDER after moving the site to the root.
