Try the new installer vm3.0.6, it may fix it.

Thanks for your reply.

Hello,
After updating from VM 3.0.4 to 3.0.6 I got the same error 1242 as Bambino.
My back-end turned to white now displaying error message up in the blue. 

Thanks to the information in this thread I was able to get the back-end working again. :-)
(although I found it scary to go for the first time into a database and actually deleting a line - did back-up the database)

Now I am left with a double VM entry in the Component-dropdown menu.
What should I do to delete one of them?

1st - as you did - back up everything

then search in your #__menus table for duplicate entries for the com_virtuemart ext .. delete the older of each one

Thanks GJC, worked perfectly.
There were two sets of com_virtuemart that I had to delete.
Left the last set in the database ###_menu and all works well now.

Excellent - see - you'll become a top gun at DB manipulation now...

I just tried to update to Virtuemart 3.0.9, and got this 1242 error. I noticed from this thread that doing the following seems to work:

"try disabling in the extensions table the VM admin menu module"

"After deleting the module mod_vmmenu from the table extensions everything goes"

Since I am more of a graphic artist than a web developer, can anyone simplify this a little more? A screenshot of where I can make this change would be great!

I am assuming I am not the only newbie out there, so there might be other people who might find a simpler explanation more useful.

Thanks again for your help.
