We can't save the customer. in magento 2

[developer-new]

Hello,
can anyone help me?
When any register into my testing site it displays an error "We can't save the customer." message.
But when I checked into backend the customer is registered.
I don't understand what is the problem.
If anyone knows, please provide the solution.
