Ran into this the other day, when upgrading (in Place) a SharePoint 2010 environment. The following was logged in Central admin and the screenshots below were the fix (you could also modify your web.config directly).
|
Title |
Web.config file has incorrect settings for the requestFiltering element. |
|
Severity |
1 – Error |
|
Category |
Configuration |
|
Explanation |
The requestFiltering element in web.config must have the allowDoubleEncoding attribute set to true in order to support file names with the + character in them. Also, it must have a child requestLimits element with the maxAllowedContentLength attribute set to 2147483647 to avoid interfering with file uploads. |
|
Remedy |
Ensure the requestFiltering element exists in web.config, that its allowDoubleEncoding attribute is set to true, that it has a child requestLimits element, and that its maxAllowedContentLength is set to 2147483647. For more information about this rule, see “http://go.microsoft.com/fwlink/?LinkID=163442“. |
