Add Category page breaking, cannot add a category

-- url of the page with the problem -- : www.redzebrafashion.co.uk/shop/administr...kashop&ctrl=category
-- HikaShop version -- : HikaShop Starter: 2.2.3
-- Joomla version -- : Joomla! 3.2.1 Stable
-- PHP version -- : 5.3.27
-- Browser(s) name and version -- : Firefox

When I click on the new button in the administartor > Category pnale, I get a broken page (attached).
I have previously been able to add categories without problems.
Any ideas?

This looks like a bug of your HTML editor. Go in the HikaShop configuration and change the "editor" option to another editor than the default one of your website and it should work.

Thanks for the quick response, fixed!
Cheers!
