I m not sure why the accepted answer was accepted if the suggested solution did not and does not solve the issue  There can actually be two related issues related to this topic   Issue  1  The master page  e g   Layout cshtml  has a section defined and it is required but the inheriting views did not implement it  For example   The Layout Template   lt body gt         Visible only to admin users         lt div id  option box  gt              this section is required due to the absence of the second parameter             RenderSection  OptionBox         lt  div gt   lt  body gt    The Inheriting View  No need to show any code  just consider that there is no implementation of  section OptionBox    on the view   The Error for Issue  1  Section not defined   OptionBox     Issue  2  The master page  e g   Layout cshtml  has a section defined and it is required AND the inheriting view did implement it  However  the implementing view have additional script sections that are not defined on  any of  its master page s    The Layout Template  same as above  The Inheriting View   lt div gt     lt p gt Looks like the Lakers can still make it to the playoffs lt  p gt   lt  div gt   section OptionBox    lt a href   gt Go and reserve playoff tickets now lt  a gt     section StatsBox    lt ul gt       lt li gt 1  San Antonio lt  li gt       lt li gt 8  L  A  Lakers lt  li gt   lt  ul gt      The Error for Issue  2  The following sections have been defined but have not been rendered for the layout page    Views Shared  Layout cshtml    StatsBox   The OP s issue is similar to Issue  2 and the accepted answer is for Issue  1

It occurs basically when  Layout cshtml is without       RenderSection  scripts   required  false    or with   RenderSection  scripts       WITHOUT   required  false   So  Just add      RenderSection  scripts   required  false  in  Layout cshtml  and it works specially for those developers who works with Kendoui genarated projects

It appears that there is a mismatch between the View files that some versions of Visual Studio auto-generates for you when you use it to create a new Model  I encountered this problem using the new VS 2013 Community Edition and walking through the W3Schools tutorial at http   www w3schools com aspnet mvc app asp but the comments above indicate that its not a problem with the tutorial directions or with a single version of VS   It is true that you can make the error message go away by just removing the   Scripts Render    bundles jqueryval     line from the create edit layouts that were autogenerated by Visual Studio   But that solution does not address the root cause or leave you in a good place to do more than finish walking through the tutorial  At some point  probably fairly early  in the development of a real application  you are going to want access to the jquery validation code that the commenting-out solution removes from your app   If you use VS to create a new model for you  it also creates a set of five View files  Create  Delete  Details  Edit  and Index  Two of these views  Create and Edit are intended to let the user add edit data for the fields in database records that underlie the model  For those views in a real app  you will probably want to do some amount of data validation using the jquery validation library before you save the record in the db  That is why VS adds the following lines    section Scripts        Scripts Render    bundles jqueryval       to the bottom of those two views and not others  The autogenerated code is trying to make the validation library available for those views  but not the others   The error happens because VS either doesn t add a corresponding line to the shared  Layout cshtml file or  see one answer above  adds it but leaves it commented out  This line is    RenderSection  scripts   required  false   If some of your views have a scripts section  as Create and Edit do   there has to be a RenderSection command embedded in the layout  If some scripts have the section and some do not  as Delete  Details  and Index do not   the RenderSection command has to have the required  false parameter   So the best solution  if you want to do anything more than just finish walking through the tutorial  is to add the statement to  Layout cshtml not remove the code from the Edit and Create views   P S  It is a bit of a confuser  here  that what is being required is in a  bundle  and the require statement looks like it is trying to include a file in a bundles folder that does not exist in your project  But  for debug builds and tutorials  that s not relevant since the bundled files get included one at a time  See  http   www asp net mvc overview performance bundling-and-minification The code that is at issue here is mentioned briefly about two-thirds of the way down the page

I think our solution was sufficiently different from everyone elses so I ll document it here   We have setup of Main layout  an intermediary layout and then the final action page render  Main cshtml  lt - Config cshtml  lt - Action cshtml  Only when web config had customErrors  On RemoteOnly  we got a custom error and no exception nor Application Error was called  I could catch this on Layout   null line in the Error cshtml  Exception was as in the question  missing scripts section   We did have it defined in Main cshtml  with required false  and Action cshtml didn t have anything that wrote into the scripts section   Solution was to add  section scripts    RenderSection  scripts   false    to Config cshtml

I have a feeling that you are rendering your section from within an  section in the  Layout file that is referring to a partial view with an  section  i e  you ve nested an  section within an  section  In the  Layout file  remove the  section around the rendersection

It means that you have defined a section in your master Layout cshtml  but you have not included anything for that section in your View   If your  Layout cshtml has something like this    RenderSection  scripts     Then all Views that use that Layout must include a  section with the same name  even if the contents of the section are empty           ViewBag Title    Title       Layout      Views Shared  Layout cshtml      section scripts         Add something here     As an alternative   you can set required to false  then you won t be required to add the section in every View    RenderSection  scripts   required  false    or also you can wrap the  RenderSection in an if block    if  IsSectionDefined  scripts          RenderSection  scripts

For me the problem was in my  Layout cshtml I have RenderSection inside a condition    if  theme     Red     theme     Green               lt div gt          RenderSection  Footer   false          lt  div gt         and in my child view it was without condition    section Footer           lt div gt               Html AwButton  Reject    Reject                Html AwSubmit  Ok    Ok            lt  div gt          so irrespective of the theme  child was adding the Footer  But in parent when theme is not Red or Green it was not adding the Footer and unhanded exception being thrown

I had a case with 3 levels a la  MainLayout cshtml  lt ---  Middle cshtml  lt --- Page cshtml  Even though doing like this    MainLayout cshtml   lt head gt      RenderSection  head   false   lt  head gt     Middle cshtml   section head        RenderSection  head       and in Page cshtml defining   section head         content        I would still get the error      The following sections have been defined but have not been rendered   for the layout page      Views Shared  Middle cshtml      head     Turned out  the error was for the Middle cshtml to rely on  Views  ViewStart cshtml  to resolve it s parent layout  The problem was resolved by defining this in Middle cshtml explicitly      Layout      Views  Shared  MainLayout cshtml       Can t decide whether this would be by-design or a bug in MVC 4 - anyhow  problem was solved
