Question

I have already read the AnsweredQuestions related to ImagesNotLoading and CannotLoadImages put could not find a situation similar to mine.

I have made a full installation of twiki and the configure file seems ok but if I look at the main page in /twiki/bin/view the images are not displayed. Also, and it could be related, I can attach files but if I try to download them it shows an internal server error and in the log of the errors file I have:

Premature end of script headers: favicon.ico
(13)Permission denied: exec of '/home/blabla/cgi_bin/twiki/pub/Main/DataQAStudy/data_qa.pdf' failed, referer: http://myhostname/cgi/twiki/bin/view/Main/DataQAStudy
Premature end of script headers: data_qa.pdf, referer: http://myhostname/cgi/twiki/bin/view/Main/DataQAStudyFile does not exist: /home/blabla/public_html/favicon.ico

I suspect something is not quite right in the files that were defined but cannot find out what. In my main configuration httpd file I have the following:

ServerName myhostname
DocumentRoot "/home/blabla/public_html"
ScriptAlias /cgi/ "/home/blabla/cgi_bin/"
<Directory "/home/blabla/cgi_bin">
   Options +ExecCGI
   AllowOverride None
   Allow from all
   Order allow,deny
</Directory>
<Directory /home/blabla/cgi_bin/twiki>
     AuthType Basic
     AuthName "Restricted to XXX"
     AuthUserFile mypasswddirectory
     Require user bla1 bla2
</Directory>
include "/dataxx/twiki/twiki_httpd.conf"

In /home/blabla/cgi_bin directory I have created a softlink named twiki pointing to /dataxx/twiki. I have set the permissions as follows:

twiki directory on /dataxx is 755
twiki/bin is 544
twiki/data is 744
twiki/lib is 544
twiki/locale is 444
twiki/pub is 744
twiki/template is 544
twiki/tools is 444

The main page twiki page is protected by a apache user then it ask for twiki users authentication to be able to modify the twiki.

If you find something obviously wrong let me know...

Answer

I finally found an answer to my own question thanks to my colleagues less blind than me :-). By changing in the configuration file LocalSite.cfg the following:

$TWiki::cfg{ScriptUrlPath} = '/cgi/twiki/bin';
$TWiki::cfg{PubUrlPath} = '/cgi/twiki/pub';

by:

$TWiki::cfg{ScriptUrlPath} = '/twiki/bin';
$TWiki::cfg{PubUrlPath} = '/twiki/pub';

it all works now and I can see both images and download properly files that have been attached.
