 Do not change Post render combining settings - Combined resource of CSS and script files after Form has been rendered, delivered as one file to the browser. This setting can be disabled by changing the value of the first tag to false for debugging purposes, but the rest of the settings should always stay as it is. This setting should be disabled when the "UseBundledFiles" setting is set to false.  N/A

<add key="Forms.PostRenderCombining.IgnoreLoadErrors" value="false"/>

 * Yes Post render combining settings - When set to false (the default) and any resources being loaded for combining fail, a 500 (Internal Server Error) response code is returned to the browser along with the combined resource response resulting in none of the successful combined resources to be available to the browser. When set to true any errors that occurred when loading resources for combining will be ignored, and the final response that is sent to the browser will have a 200 (OK) response code resulting in resources that didn't fail to load still being available to the browser. One of the following:
  • true
  • false

<!--<add key="Forms.PostRenderCombining.RelativeRootOverride" value="[RelativeRootURL, e.g. "http://cdn.host.com/"]"/>-->

 Yes RelativeRootOverride - used when the server cannot access the individual js and CSS resources it needs to build the combined resource (PostRenderCombining), using the external root URL (such as http://www.k2.com), but rather must use an internal root URL(such as http://internal.k2.com). When the combined resource's functionality does not have access to the resources using the external URL, this may result in the 500 errors on CombinedResources.ashx requests.   URLs such as http://internal.k2.com
* You can change these values but it's not recommended
