virtuemartModelCategories error

[frankiep]

Hello i'm a new VM user. All right till now but i have a little problem on my website. I have searched about a similar problem without results.

I have installed VM 2.0.18a on Joomla 2.5.9. Php version 5.3.3-7+squeeze14

My problem is that in the categories list i see an annoying message that says "Model class virtuemartModelCategory not found in file" (i use italian language but the english version of the error is this). I have attached a screen to help you to understand.

Thanks in advance
