Incorrect format parameter

Currently, when I visit localhost/phpmyadmin, I am seeing the following error:

ERROR: Token Mismatch (In tooltip)

Incorrect format parameter

I will explain the changes I did step by step:

I had xampp of version 1.7.1 installed.
To upgrade it to latest, I renamed Xampp folder in c:// to "xampp_1" and took the group database backup in .sql format.
From this link, I downloaded php_oauth-1.2.3-5.6-ts-vc11-x86.zip and copied the php_oauth.dll to c://xampp/php/ext/ and then in php.ini, I mentioned extension=php_oauth.dll.
After this, I ran Apache server and Mysql through Xampp. then tried to import the sql backup file through CLI as follows:
```
  mysql -u root < localhost.sql
```
I got some error in command prompt. (I will update this soon)
Then later when I visited localhost/phpmyadmin, I am seeing this page:

I uninstalled both 1.7.1 and 5.6.3 and then re-installed 5.6.3. That did the trick.
