You may either create missing directories and chmod directories manually to 777, or run one of the sets of commands below.
Execute the Tiki installer again after you run the commands below.

If you cannot become root, and are NOT part of the group :
        $ bash
        $ cd 
        $ chmod +x setup.sh
        $ ./setup.sh yourlogin yourgroup 02777
        Tip: You can find your group using the command 'id'.

If you cannot become root, but are a member of the group :
        $ bash
        $ cd 
        $ chmod +x setup.sh
        $ ./setup.sh mylogin 

If you can become root:
        $ bash
        $ cd 
        $ chmod +x setup.sh
        $ su -c './setup.sh '

If you have problems accessing a directory, check the open_basedir entry in 
/etc/php5/apache2/php.ini or httpd.conf.

Once you have executed these commands, this message will disappear!

Consult the tikiwiki.org installation guide if you need more help.

Execute the Tiki installer again if you have completed the steps above.
