[Mediawiki-l] The upload directory (public) is not writable by the webserver

[Massimo Canonico]

Hi,
I got this error even if I followed the instruction on
http://www.mediawiki.org/wiki/Upload

First of all, that "public" means that wikimedia is expecting to use a 
directory called "public"? I have installed mediawiki from tgz file, 
without change the default values. How is it possible? If it is related 
to images directory, that error messagge should be fixed.

-- I set"755" for folder images:
dcs:~/dcs.di.unipmn.it/mex/mediawiki $ ll | grep ima
drwxr-xr-x  2 mex    mex      4096 2010-01-28 11:20 images

-- I have enabled upload:
$wgEnableUploads  =  true;

-- I have checked Apache aliases

-- I have checked  file_uploads on php.ini

but still the same error message appear.

Any suggestion?

Thanks,
  Massimo
