Joomla Registration error

if i register as user using another component then bellow two messages are appearing
>> Login denied! Your account has either been blocked or you have not activated it

and

>>thankyou to became User

and activation link sent to user email address.

how can change Login denied message?

Thankyou to became User is component message

how to disable "Login denied! Your account has either been blocked or you have not activated it" this message

These are not Joomdle errors. I suggest you use the normal Joomla login and make sure everything works normally before you use any 3rd party component registrations. Also, using a 3rd party registration / login may not work with Joomdle depending on how it works.
