Hi

We are currently having issues adding to our basket on a new website. This has been working and then all of a sudden it stopped. We are running the latest version of both TeaCommerce and Umbraco so we are no a little lost. We did notice that the TeaCommerce section had disappeared within the CMS, but it was showing as installed within the packages section. We added some lines into the applications.config and tress.config in order to get the icon on the left hand side to show and we can now see our shop again within the CMS.

The error message we are getting back from FormPost.aspx is

    <error><![CDATA[MESSAGE:

Any help would be appreciated as we were meant to put the website live today.

Thanks Richard
