I am connected to ERP LN using WebTop as client. Trying to start sessions result with error for every session: "Failed to retrieve form class from backend ..."

Any idea?

I think you had run Create Action in Webtop server side.
So you can delete that directory, then it will run.
I know it's stranger, maybe it's a bug.

Hi,
I am also having the same problem. Could you please explain which folder as to be deleted.

Thanks,
Thamarai
