Thanks for replying Anshu.
In my search for a fix, I have already come across and read this page – and many other similar threads and pointers. Unfortunately, I am not a WP developer or coder – so this and other proposed solutions are couched in terms that are incomprehensible to me.
Surely as there is no host/server involved here - it must be a simple process to fix? I was hoping for a step-by-step, idiot-proof solution. Thanks.
