Settings not saving between page updates in the theme options

Hi,

I'm working on a new site (http://happyhooligans.ca) and have installed Atahualpa 3.7.13 and working in wordpress 3.8.1

I am customising the design working from the top of the site down - The header I have customised so as to include 2 widget areas which I have created and saved - I can then alter the alignment of these save and then go to remove the left sidebar in the style & configure sidebar settings - as soon as I save these settings the alignment of the header widgets is removed reverting back. If I then change the settings for the style & edit HEADER AREA and save then the settings for the sidebars are reverted back to the original.

I have also edited the category menu and the same thing happens previous settings are removed and only the latest settings are applied.

I have tried resetting all theme settings and also importing from an existing atahualpa settings and this hasn't worked either.

I have contacted the host company and they have no idea please help as this is my first encounter with this happening (I use Atahualpa a lot and have never encountered this issue previously)
