I've searched around but I can't seem to find an answer. I've deployed a JumpBox ESX template with Joomla 1.5.9. I just purchased JMS, but I'm getting a permissions problem during the install.

I get JFolder::create: Could not create directory
Unable to create the directory '/var/data/joomla15/multisites'

The Joomla15 directory permissions are:
drwxr-xr-x 16 admin www-data 4096 Mar 3 16:10 joomla15

I'm logged in Joomla as Admin.

Any help is appreciated.

The problem of permission my be due to the fact that the owner use by Joomla is not the same thanthe one corresponding joomla15.
For the moment, only the owner "admin" can create files and folders.
The other owner can only read.
I suspect that the user of you apache or windows used in Joomla is probably different of this user.
Perhaps you should increase the permission with a chmod 777.

Sometimes, when you have just create a "fresh" joomla and you have transfer it by FTP, you may perhaps have used an "admin" account with a "root" privilege.
As your HTTP server (apache, IIS) has less permission, the fact to have installed Joomla with a super user, this does not allow the normal user to modify its content.
You may perhaps have to use the Joomla FTP layer to allow increase the permission when using the "admin" login and password in the FTP. See Joomla Global Configuration / FTP configuration. See the tutorial that help you in the FTP configuration.

I also suggest you perform some seach in this forum with permission.
You probably find answer that will help you as this is a very frequent question to which I have replied many time.

Thanks for the quick reply.

I changed the owner to www-data.www-data and things are ok.

Hello! I have a problem with JMS. On the page Checkpatches i found the table with trouble files. Some of these files not found! And it notes to add the file. Like this, for example: includes/defines_multisites.php, installation/includes/defines.php, installation/installer/helper.php, installation/installer/jajax.php.
I haven't found these files in the archive com_multisites_V1.1.7.zip. Please, help me! What can i do?

Those files are present in a tar.gz file located into the /administrator/components/com_multisites/patches/xxx where xxx is the version of your Joomla.
