Blogger vs WordPress Blog

Are you referring to this site https://theshanmarielife.wordpress.com/?

It seems it was registered by https://en.forums.wordpress.com/profile/theshanmarielife

You have to be logged in as Admin http://en.support.wordpress.com/user-roles/#administrator under the exact same username account that registered the blog to access the blog's dashboard. The Admin login link to the dashboard for every blog hosted by wordpress.COM is:

http://NAME_OF_BLOG.wordpress.com/wp-admin/

* You will have to replace "name_of_blog" with the actual blog's name in that URL.

I recommend bookmarking that link or memorizing it.

You can update your email address here https://wordpress.com/me at any time.

If you are not logged in under the correct username account then clear your browser cache https://en.support.wordpress.com/browser-issues/#clearing-your-browser-cache and cookies https://en.support.wordpress.com/browser-issues/#clearing-wordpress-com-cookies and then login correctly under the relevant username account.

If you did not register the site under your username account and do not have the required access, then you need to contact the person who registered the account and site under it, and have them act or transfer the site to your username account by using this process. http://en.support.wordpress.com/moving-a-blog/#transferring-your-blog-to-another-user-or-account

If the login information has been lost go tohttps://en.support.wordpress.com/passwords/https://en.support.wordpress.com/passwords/#lost-password

If you check each and every possible email address and account and are not successful gaining access to the blog(s) then you must complete the form for account recovery at this link https://en.wordpress.com/wp-login.php?action=recovery and submit it to the Account Recovery Staff, and provide proof ownership, so they can contact you by email ie. not on these public support forums, which are available to everyone with internet access.

Support Staff cannot breach the privacy policy and provide the log-in information. You have to provide proof ownership to Account Recovery Staff to gain access https://en.support.wordpress.com/account-recovery/
