Getting an error 404 when saving changes at Clients Profile -> Products/Services

[datex]

When I want to make a change to Products/Services (clients profile) I keep getting a 404 error. But If I first save changes to contacts for the same client (getting a validation error "A user already exists with that email address") - and when makes the changes to Products/Services I don't get the 404 error.

 

Any who have also experienced this?

When you submit the change and get a 404, is the change applied if you check again? I'm having a similar issue with many actions. I see a 404, but the changes do seem to be applied.

Just checked. But this time I didn't get the 404 error
