I'm getting the following error:

Could not load file or assembly 'WebPartsAndControls, Version=, Culture=neutral, PublicKeyToken=e2637de7f0074503' or one of its dependencies. The system cannot find the file specified.

How should I go about tracking down the issue?

  • Where you are getting this error and what action produces this? Dec 2, 2014 at 13:43
  • When I view any of my store front pages under my subsite. It doesn't matter if I am logged into share point or not.

  • It seems there is a webpart that is causing this issue. At the end of the page add contents=1. This will give you the list of webparts. Remove the webparts you are not using. Dec 2, 2014 at 13:49
  • thanks, but when I add that to the URL, it tells me "There are currently no Web Parts associated with any Web Part Zones on this page. Web Parts added to the page outside of a Web Part Zone will not appear in this list."

    Ok in that case open up the corresponding master page & page layout. Check if there is any reference to the assembly WebPartsAndControls, Version=, Culture=neutral, PublicKeyToken=e2637de7f0074503 Dec 2, 2014 at 13:54

This can happens because of any of the following issues

  1. A webpart that is embedded on the page. To find all webparts add contents=1 at the end of the page URL
  2. Check the Page Layout and see if any reference is there for the mentioned assembly
  3. Check the master page and see if any reference is there for the mentioned assmebly
