Fatal error: Call to a member function tail() on a non-object
Bonjour à tous,
J'ai le message d'erreur suivant à l'ouverture du site:
Fatal error: Call to a member function tail() on a non-object in /home/xxxx//www/imagevue/include/ivXmlParser.class.php on line 91
Hors j'ai deux site identiques, un marche et l'autre me mets cette erreur. Ces deux sites sont sur le meme serveur, meme configuration.
Where is the problem ?
