I have just upgraded to the latest version od Smith Cart 5.44.0 on a staging site http://soapqueen2011.digdnn.com.
Now when I click on a product from any Buy Now module I get an errror "The webpage at http://soapqueen2011.digdnn.com/Default.aspx?tabid=135&def=ErrorMessage has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer."
I cant see any way to fix this.
Any ideas

Please take the following steps to resolve this issue:

1. From the store admin menu, click on the page template button to go into the page template editor and delete all your page templates.

2. In file explorer, navigate to your \portals\[portalid]\smithcart\tenplates folder

3. Delete all the files in the \portals\[portalid]\smithcart\templates folder

4. Reset iis and restart the application from the dnn host menu

5. Go to product listing page and see if your products are displayed.
