Requirements problem

The following errors must be resolved before you can continue the installation process:

  • The directory sites/default/files is not writable. An automated attempt to create this directory failed, possibly due to a permissions problem. To proceed with the installation, either create the directory and modify its permissions manually, or ensure that the installer has the permissions to create it automatically. For more information, please see INSTALL.txt or the on-line handbook.
  • Multibyte string input conversion in PHP is active and must be disabled. Check the php.ini mbstring.http_input setting. Please refer to the PHP mbstring documentation for more information. (Currently using Unicode library Error)

Please check the error messages and try again.
