From time to time you may recive an error message:
Unknown server tag 'WebXelCart:????'
Where ???? will be the class name of one of the carts server controls, the most likely cause for this is that Register TagPrefix line is missing from the page, to cure this edit the server control tag with the appropriate tag editor dialog and the Register TagPrefix line will be re-inserted into the page.
Alternatively you can copy and paste it from here into you page, the Register TagPrefix line required is shown below:
<%@ Register TagPrefix="webxelcart" Namespace="WebXelCart" Assembly="WebXelCart" %>
Lite Version:
<%@ Register TagPrefix="webxelcartlite" Namespace="WebXelCartLite" Assembly="WebXelCartLite" %>
