I got this error because I found out that I referenced jQuery twice   The first time  on the master page   Layout cshtml  in ASP NET MVC  and then again on one current page so I commented out the one on the master page   If you are using ASP NET MVC this snippet could help you     Scripts Render    bundles jquery      comment this line   Scripts Render    bundles bootstrap    RenderSection  scripts   required  false    and in the current page I added these lines   lt script src    scripts jquery-1 10 2 js  gt  lt  script gt    lt  --  region datatables files -- gt   lt link rel  stylesheet  type  text css  href    cdn datatables net 1 10 12 css jquery dataTables min css    gt   lt script src    cdn datatables net 1 10 12 js jquery dataTables min js  gt  lt  script gt   lt  --  endregion -- gt    Hope this help you even if don t use ASP NET MVC

I ran into this error also   For whatever reason I had originally coded   var table       myTable   DataTable        paging   false       order      4   asc           This would not throw the error sometimes and other times it would   By changing code to       myTable   DataTable        paging   false       order      4   asc           Error appears to have stopped

CAUSE  There could be multiple reasons for this error    jQuery DataTables library is missing  jQuery library is loaded after jQuery DataTables  Multiple versions of jQuery library is loaded    SOLUTION  Include only one version of jQuery library version 1 7 or newer before jQuery DataTables   For example    lt script src  js jquery min js  type  text javascript  gt  lt  script gt   lt script src  js jquery dataTables min js  type  text javascript  gt  lt  script gt    See jQuery DataTables  Common JavaScript console errors for more information on this and other common console errors

Having the same issue in Flask  I had already a template that loaded JQuery  Popper and Bootstrap  I was extending that template into other template that I was using as a base to load the page that had the table  For some reason in Flask apparently the files in the outer template load before the files in the tables above in the hierarchy  the ones you are extending  so JQuery was loading before the DataTables files causing the issue  I had to create another template where I run all my imports of JS CDNs in the same place  that solved the issue

Honestly  this took hours to get this fixed  Finally only one thing worked a reconfirmation to solution provided by  Basheer AL-MOMANI   Which is just putting statement       RenderSection  scripts   required  false    within  Layout cshtml file after all  lt script gt  lt  script gt  elements and also commenting the jquery script in the same file  Secondly  I had to add     noConflict      within jquery function call at another   cshtml file as      document  readyfunction                  noConflict                  example1   DataTable                 example2   DataTable                  paging   true                 lengthChange   false                 searching   false                 ordering   true                 info   true                 autoWidth   false

There can be two reasons for that error   First  You are loding jQuery DataTables js before jquery js so for that  -  You need to load jQuery js before you load jQuery DataTables js   Second  You are using two versions of jQuery js on the same page so for that  -  Try to use the higher version and make sure both links have same version of jQuery

I know its late Buy can help someone  This could also happen if you don t add     myTable   DataTable    inside the document ready  So instead of this      myTable   DataTable     Try This    document  ready function             myTable   DataTable

if some reason two versions of jQuery are loaded  which is not recommended   calling   noConflict true  from the second version will return the globally scoped jQuery variables to those of the first version   Sometimes it could be issue with older version  or not stable  of JQuery files  Solution use   noConflict      lt script src  js jquery js  type  text javascript  gt  lt  script gt   lt script src  js jquery dataTables js  type  text javascript  gt  lt  script gt   lt script gt    noConflict    jQuery  document   ready function                myTable   DataTable           Code that uses other library s   can follow here   lt  script gt
