If you experience the below error while creating an Umbraco package Root element is missing. I had this problem a while ago, check your /App_Data/packages/created/createdPackages.config Mine was an empty file so I added the following; <?xml version="1.0" encoding="utf-8"?> <packages></packages> Then I could create packages without getting the above error.

ISAPI URL Rewriting If for any reason, friendly urls are not being parsed and are not having a page displayed, it maybe the case that the ASP.NET ISAPI filter is not configured properly. In order to correct, a new application extension mapping is required on the IIS website. This can be found in "Home > Configuration > Insert Wildcard Application Map". The executable path should be as follows: "C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" and the "Verify that file exists" property should be unchecked.

A problem may arise when using Windows 7, IIS 7 and EPiServer CMS 5. When the application refuses to start, you will receive a TypeInitializationException. I think this is caused by the global application start method trying to access the Data Factory class when unavailable.

In order to submit .NET forms from a Fancybox, validation and postback has to be manually triggered to perform the desired behaviour. Because a .NET form is rendered outside the page's form element, the form won't know where to post to.

I recently had a scenario where by I required a Fancybox to appear after validation had been executed within a standard ASP.NET form. The difference being that I wanted the Fancybox to only appear if validation had been successful. In order to solve the problem, I had to add an extra function to the 'onclientclick' property of the form's submit control and manually trigger the web form validation function.

It turns out that all versions of Internet Explorer do not like self closing script tags or as the Internet world calls it, element minimization. Self closing script tags are perfectly valid XHTML elements, but invalid HTML elements. Internet Explorer only supports XHTML to the extent that only HTML-compatible markup is possible. All other major browsers support XHTML markup.

Recently I encountered a problem whereby viewing thumbnails for images within EPiServer's file manager would not render correctly. After investigating as to why this problem occurred, I found that the issue was due to incorrect permissions on the '/util/temp/thumbcache/' folder within the site's application folder.
