Error- Bad Parameters on Request in Clarity 15.4.1 with IE11

Products

• Clarity PPM On Premise

Issue/Introduction

Clarity PPM might stop working in several scenarios in Internet Explorer (IE11) :

• Symptom 1: The following error in Classic UI:

 "The server was unable to parse the parameters on the URL or from a form. This may be caused by too many parameters on the URL or form - the maximum allowed is 10000. The request has been rejected." 
Several actions might cause this error:

1. Restore Defaults on the Overview Page. 
2. Admin -> Objects -> Project or Idea object -> Views -> Click on Fields Icon corresponding to any layout, and now Click on Return. 
3. Add new attributes to an Object.
4. Searching for attributes in an object.
5. Saving Team's properties on a Project.

• Symptom 2: Users are unable to upload documents to project space in the Collaboration tab

Note: This does not occur on every exact same scenario or on all Projects, but might be consistently encountered.
