A binding instance has already been associated to listen URI .after moving from .NET 4.0 to 4.5 - wcf

Question

After 3 days of never ending search I am posting this. Please help. The following is the config file I have. There is only one endpoint specified , but its saying there is a conflict in the endpoints. Please help me rectifying this conflict.
System.InvalidOperationException: A binding instance has already been
associated to listen URI
'http://dd.myserver.net/MyWebService/MyService'. If two endpoints want
to share the same ListenUri, they must also share the same binding
object instance. The two conflicting endpoints were either specified
in AddServiceEndpoint() calls, in a config file, or a combination of
AddServiceEndpoint() and config.

Finally I resolved the error given by one guy [https://stackoverflow.com/questions/12643113/wcf-conflicting-endpoints-after-net-4-5-installation/39394010]
I have just removed the security tag inside
before
<webHttpBinding>
<binding maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647"/>
<security mode="None">
</security>
</binding>
</webHttpBinding>
After
<webHttpBinding>
<binding maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647"/>
</binding>
</webHttpBinding>
This little thing took me 3 days of search. thanks to stackoverflow.
