Some terrible things happen to our new website! Please have a look and help us.
The url of the website is
The header is designed by using Dropdown Box plug-in. The layout of the main categories of the subdirectories should be horizontal, which is similar as our current website http://www.westkin.com/. And it was, until we installed some other plug-ins. The layout became vertical. We have uninstalled the plug-ins, but the problem still exists. I guess it may because during the process of instalment, it changes the coding, which can not be recovered.
Can anybody give me some suggestion about how to return the style to originals?
Thank you for your help in advance!
