Product edition impossible after site upload

[abinoe]

I created the site offline (using wamp) : it works well (Joomla 3.4.8 & VM 3.0.12)
But, once online (and after having updated configuration.php & Vm Safe path), when I enter the administrator backend, VirtueMart, Product and try to edit a product (by clicking on it), I get this :
Fatal error: Class 'VirtueMartModelWaitinglist' not found in .../administrator/components/com_virtuemart/helpers/vmmodel.php on line 545 (... replaced for this forum)

Do you know what my problem may be ?
According to Google, it seems I'm the only one on earth to have this problem ...

Thank you for your answers !

or you just need to turn off error reporting
