Hi
We recently upgraded from 1.4 to 1.5. Most pages are working fine, except the product pages (we have only a few test products in there right now). When I click on a product, I get the standard error.
We get a "We're sorry, an internal error occurred that prevents the request to complete."
The system log has the following details:
Exception of type 'System.Web.HttpUnhandledException' was thrown.
Exception: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.InvalidOperationException: Only one instance of a ScriptManager can be added to the page. at System.Web.UI.ScriptManager.OnInit(EventArgs e) at AjaxControlToolkit.ToolkitScriptManager.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.AddedControl(Control control, Int32 index) at System.Web.UI.ControlCollection.Add(Control child) at NopSolutions.NopCommerce.Web.ProductPage.CreateChildControlsTree() in F:\Own\NopCommerce\EnterpriseEdition\1.5Release\NopCommerceStore\Product.aspx.cs:line 52 at NopSolutions.NopCommerce.Web.ProductPage.OnInit(EventArgs e) in F:\Own\NopCommerce\EnterpriseEdition\1.5Release\NopCommerceStore\Product.aspx.cs:line 59 at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.product_aspx.ProcessRequest(HttpContext context) in c:\windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\2c474bda\6fbbe0cc\App_Web_3qkdpj60.22.cs:line 0 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
Any suggestions of what might be going wrong?
Thanks
