Topic on Project:Support desk

Hello,

For one of my customer, I have made an upgrade of his mediawiki from 1.15 to last version. I have copy / paste the images directory but when I visit some pages, in place of thumbnails, I have "Erreur lors de la création de la miniature : Error code: -1"

If I go to the same page connected as admin, that works! I see thumbnails.

Other problem is that when I try to click on an image, I can't see file data and history but I have "

Erreur de la base de données

Une erreur de requête de base de données s'est produite. Cela peut provenir d'un bogue dans le logiciel.

Thx for your help,

Olivier

did you run the update script? See manual:Upgrading. Running it should solve database errors. If not, see Manual:How to debug for settings you can change to display more detailed error messages.

If you moved your host, filesystem permissions may be a problem, if the images have a different owner/group on the new server. You may need to fix file permissions recursively on the images directory, so the owner is the webserver user.

You can also set a debug log to see what's happening, and maybe look for any error condition there, if paths on the filesystem are correct, etc.
