Thank you so much for your quick reply. As per my knowledge, I don’t have custom code or logic hook related to users in custom folder. Is there any particular module/code file, I should check to find out about this error?
I don’t know much about this, I just searched the code and found that that error message appears inside the User bean save function. So perhaps trying to find out why it’s being called could be a good strategy.
Or you could simply ignore it, if it’s not causing any trouble.
