Ajax error with winchester black template

[bluestorm]

Hi everyone, I have a website called illumabrite.co.uk/index.php and have installed winchester black template. But when I click on the shopping cart I get the following error An unknown response null: :text/html; charset=utf-8: :SyntaxError: JSON.parse: unexpected character was received while processing an ajax call. The action you requested could not be completed.
but when I click on ok it takes me to the basket. Can anyone help with this, thanks.

See Making v154 DIY/Picaflor-Azul templates work with v1.5.5, particularly the point about using the v155 jscript_framework.php file instead of the older one. And if you're not using v155 already then also grab the new ajax.php file from v155.

Thank you very much it worked perfectly.
