JUser::_load: error bug when updating order status in backend [WITH HOW TO FIX]

You could try to use the tools to set the shopowner to another id

[status101]

I know this is an old post, but I ran into this issue today and came across this post.  I have resloved it by resetting my super admin to ID 42, BUT this is generally not a good idea ( well Akeeba Admin tools does not think so! ) .. anyway,  Milbo said:

I would love to do this, but what 'tools' do you use to set the shop owner to a different ID?  I have looked around and really cant find anything....
