change the website folder

Recently, I made my website on '' and installed wordpress on '' folder. After finishing the website using wordpress, I want to change the folder from '../wp' to '..' . So I moved all required files according to the direction of 'changing directory manual'.

After that, I have two problems.
One is that the previous theme was worked normally, but I can't to access 'admin' account. The other is that I can access 'admin' account, but the theme was not worked normally. Currently, my web site is under the second case. In addition, within my account on 'wpmudev' site, there's no information about my wordpress installation.

What's wrong and what can I do to fix the problems?
