problem vm 2.0.2 libraries / joomla / registry / registry.php online 336

[yayo76]

Hello everyone,
I have a problem with a site I'm developing with joomla 2.5.3 and vm 2.0.2. When I click on any product vm I get this error: Fatal error: Can not access empty property in / home / XXXXX / public_html / libraries / joomla / registry / registry.php on line 336 I had previously made ​​a demo site on another server where everything worked, so it may be a server issue?
Thanks
Regards
