Script error on CheckOutOnePage page.

Hi all,

I am using nopCommerce 1.90 hosted on Arvixe.
All of the sudden, we met this error at the CheckOut page (checkoutonepage.aspx) when clicking on the "Ship To This Address" button or "Next" button - the Error on Page appeared at the status bar. When double-clicking that error, we found the following details. And because of this error, we cannot go any steps further on the checkout progress.

The problem is we haven't changed anything to the source code and the site often worked normally before. Is it caused by the incorrect .NET version of the hosting - as we found only .NET CLR 2.0, 3.0, 3.5 in the above message ?

Please help. Many thanks,

Long.

hi, did you check to see if you are running your store in .net4.0   ?

you will need to set this via the control panel on your hosting account

Yes, I tried both ASP.NET 4.0 and 4.0 (Integrated Pipeline).
The whole site works, but this CheckoutOnePage page, with that script error.

I have spent quite some time to google this problem and not found any other solution than to remove the Ajax code, I have seen similiar errors in nop on the productpages where the user can rate the product, I removed that ajax code and my error was removed.

Would be good to hear if someone actually found a fix for this problem.

I'm having the same problem here.   :(

Yes I also got an error and switch off one-page checkout for now.
A

I have the same bug.

Hi guy !!
Ok after some verification, I confirm that it's not a bug in the NopCommerce solution, it's only because we have made some modifications in the theme, For my case this bug was caused by Response.write () putted in the wrong place.

My response.Write() change my page between the ajax call and response and this page should not be changed when an ajax call is made.

Good luck to find wich change you have made to bug this page :)
