@dippatel4594,
Not sure from here what can creating the problem.
It only shows a problem registering the user.
Have you tried to create it from WP dashboard?
for my site, the user is not able to register itself.
while he trying to create a new user following error popup is occurred.
“Something strange has occurred while created the new user”
for a practical example I am sending registration link for my site, can you please check it??

I would be able to see the error but not the detail of the problem. So this provides me any useful info.
This error can only be thrown by a failure in the user’s creation (due to some restriction), or by security because the anti-spam honeypot has popped up, which would only happen if a robot or other plugin filled in the hidden “website” field for this purpose. It sounds to me like it could be a compatibility problem with some other installed plugin, could you please check that?
