User setup successful!
Now you can log in with the login “admin” and password “bff5ec”.
Note that password carefully! It is a random password that was generated just for you. If you lose it, you will have to delete the tables from the database yourself, and re-install WordPress.
Were you expecting more steps? Sorry to disappoint. All done!
please help…..thanks from argentina !
