# TemporaryStreamWrapper error during installation

In continuation to my previous question https://drupal.stackexchange.com/questions/208245/openatrium-installation-profile-error

I have another problem in the very next step i.e. during Site Configuration.

• Firstly the theme seems to have broken because CSS is not being applied.

• Secondly, I'm getting the error message.

"Warning: file_put_contents(temporary://fil3BF3.tmp): failed to open stream: "DrupalTemporaryStreamWrapper::stream_open" call failed in file_unmanaged_save_data() (line 1936 of \includes\file.inc).

•The file could not be created."

I understand from some other posts that this is due to missing permissions on "sites/default/files" folder. But this folder is created on the fly during installation how do we give access to it. In addition, I believe another possible cause can be due to permissions to "tmp" folder. Most of the other posts mention changing that path in "Admin -> configuration" somewhere, but for that OpenAtrium needs to be completely installed. Where can I change the path for "tmp" file through file system.

$conf['file_temporary_path'] = '/tmp';  In Addition, all item stored in variable table in Drupal site's database can be set with $conf array in the same way.
