Hi, I installed mediawiki for local use only, just to try the software
and learn how to use. I uploaded two files and created a new page that
uses these files. All was ok. But when I did this API query on my browser:
http://localhost/wiki-1/api.php?format=xml&action=query&titles=File:Hyph.png&prop=imageinfo&iiprop=url
I get this page with error message:
############ start of error message ############

It seems the error happends when it is traing to create the
'imagerepository' element of the result page.

It happens the same for the other files. I tried looking for help on
Internet but without succes.
I don't understand: the files exist in my "images" directory and the
page I created shows them.
I thought maybe I must explicitly create the local repository object of
images and therefore I tried to put this code in my LocalSettings.php:
$wgLocalFileRepo[] = array(
'class' => 'LocalRepo',
'name' => 'local'
);
but in this case I get a full white page.
Here are versions of my software:
O.S.: Debian GNU/Linux testing
apache: 2.2.22
php: 5.4.4
mysql: 5.5.24
mediawiki: from git (1.20alpha) but I tried also with 1.19.1
At the end of this e-mail I put my LocalSettings.php.
Thanks for any help and excuse me for my bad english.
