Every time that I try to upload files I get a error:

Warning: mkdir() [function.mkdir]: open_basedir restriction in effect.    
File(/home/softsite/public_html/images/8/89) is not within the allowed path(s):
(/home/restricted/home/softsite) in
/home/restricted/home/softsite/public_html/ciclopes/wiki/includes/Image.php on
line 726

Warning: move_uploaded_file() [function.move-uploaded-file]: open_basedir
restriction in effect.

/home/restricted/home/softsite/public_html/ciclopes/wiki/includes/SpecialUpload.php
on line 316

The doubt is how can I configure the MediaWiki to upload to another directory?

I try to change the $wgUploadPath and $wgUploadDirectory to the correct
directory but didn't work...

How can I do that?

Thanks in advance
