RefTagger control panel does not work on my site

When selecting the Bible version and pressing the SAVE button on the control panel, nothing happens and the Bible version remains as KJV. If I put a tick against Libronix and press SAVE, nothing happens there either. This can be seen on page: http://www.inthebeginning.org.uk/wine.html
In addition, I have tried a page without the control panel, but in spite of having selected NKJV for the default Bible version, I still get KJV in all the pop-up boxes. This can be seen at http://www.inthebeginning.org.uk/Born%20again.html
I understand very little about HTLM and have created the site with Serif's WebPlus X4, so that may be the problem. But I am beginning to despair of ever getting the excellent RefTagger to work properly on my site. If there is a solution to this, I would be very grateful to hear it.
