install problems

Hi there! I've successfully installed the Demo version of Jollyness on my Mac - no problems. However, I'm running into problems on our public hosting server - there, I'm seeing two big problems and some minor problems (which are probably side-effects of the big problems). For my local installation, I followed the steps in the docs at: Documentation/index.html#!/installation. When everything was working, I copied the files to our public hosting server, set up the database and settings.php there and checked file and folder permissions. Mostly the demo shows up OK, but I do see this first problem on the main page, just below the main floating menu: Warning: file_put_contents(temporary://filewFW6R3) [function.file-put-contents]: failed to open stream: "DrupalTemporaryStreamWrapper::stream_open" call failed in file_unmanaged_save_data() (line 1941 of /home/centric/drupal/includes/file.inc). The file could not be created. The second problem is that I cannot navigate to http://myhost/user or any other sub-URL. For example, if I click on the link to one of the Blogs, I see this page: Not Found The requested URL /blog-mansory was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. One thing I tried - since the error message for the first problem indicates that Drupal can't create a temporary file - I took a look in the database, in the table "variables", at the value of the row for "file_temporary_path". The value provided in the database.sql file which comes with the Demo says: ('file_temporary_path','s:17:"/var/zpanel/temp/";') I updated this with the value: ('file_temporary_path','s:45:"/home/centric/drupal/sites/default/files/tmp/";') Unfortunately, this hasn't made a difference, and I'm out of ideas. I've checked file and folder permissions - can't see anything wrong there. Any ideas or suggestions gratefully accepted :-) Cheers, Ian
