I did do a IISReset but still got the error. Then to make sure restarted the whole server, but still same error.
Here are the SPLogs entries:
Name=Request (GET:http://nmbm-sp:2010/_admin/ListPpsTrustedDataSourceLocations.aspx?appid=a60596bd-25d0-49ea-9985-684f07cec5ec)
System.Web.HttpException: The server tag is not well formed.

Here are the entries in web.config for Central Administration:
<PageParserPaths>

Hope this helps!
