characteristics not saving

hi,

everytime I create a characteristic, it does not save - it keeps reverting back to the default value (the characteristic at the top of each list).

-- url of the page with the problem -- : www.spaldingfasteners.co.uk/categories-o...category_pathway-152
-- HikaShop version -- :2.3.0
-- Joomla version -- : 1.5.26
-- PHP version -- : x.x.x
-- Browser(s) name and version -- : firefox
-- Error-message(debug-mod must be tuned on) -- : Error_message

Hi,

First of all thanks to update your HikaShop version, if the problem still persist thanks to set the Joomla error reporting level to "maximum".
