Bonjour,

Peux-tu passer temporairement le blog en mode debug et copier ici l'erreur que tu as ?
Pour cela il faut modifier le fichier conf/_advanced.php et positionner la variable debug a 1, c'est autour des lignes 30:

/**
 * Display debugging informations?
 *
 * 0 = no
 * 1 = yes
 * 2 = yes and potentially die() to display debug info (needed before redirects, e-g message_send.php)
 *
 * @global integer
 */
$debug = 1;

Bonjour Slamp,

Merci d'avoir pris le temps de me répondre. J'ai fait la modif dans le fichier conf/ advanced.php et voici ci-après le message d'erreur qui apparait maintenant. Merci par avance si tu as une idée pour résoudre le problème.

Une erreur inattendue est survenue!
Si cette erreur persiste, merci de la signaler à l'administrateur.

Peux-tu verifier que dans l'interface d'administration, le file manager est bien actif ainsi que la possibilite d'upload ?
Cela doit etre dans App Settings | Files
Si c'est le cas, essayes d'activer les options enable root directories for blogs, for users, enable creation, etc etc...
(je ne me rappele plus vraiment ce qu'il y a comme option dans la version 1.8.6)

A l'occasion penses a repositionner la variable debug a 0.

Bonjour Slamp et merci de ta réponse.
J'ai vérifié dans l'interface d'administration : les permissions des utilisateurs me semblent OK et les paramètres de création de fichiers et de répertoire médias aussi. Mon autre site http://www.ras-le-bol.fr qui a été créé directement en version 1.8.6 n'a pas ce problème d'uploading.
Donc cela tient manifestement à la transformation de 0.9 en 1.8.6.

Slamp,
J'ai trouvé une solution de "contournement". Ce n'est pas forcément satisfaisant mais cela me permet d'agrémenter mes billets d'une image et d'attendre mon retour de vacances pour régler ce problème et l'autre (perte du texte à la prévisualisation). Encore merci et bonnes vacances
