When trying to setup a sub portal for a user on a DNN 4.9.2 system setup to provide hosting I get the following error:

Connection Interrupted
The document contains no data.
The network link was interrupted while negotiating a connection.
Please try again.

The system seems to get caught up after setting the template option in the portal creation tool area,
after a minute or two it spits back the error-document contains no data.
To work around this how does one disable the template option?

Currently it does not allow me to setup a sub portal without specifying a template.

Does anybody know what could possibly be causing this problem?
I have noticed notice bunch of errors in event viewer I am none the wiser as to whether or not they are connected to this issue.

The errors are a combination of:

InnerException: Object reference not set to an instance of an object.

Initially these errors were occuring every minute of the day until I tweaked DotNetNuke.Services.Search.SearchEngineScheduler

The main issue that really needs resolution is the first error as this is preventing sites from being setup.
