Nodes in tree view not expanding

Bernhard Herzig asked on June 14, 2017 22:44

We deployed a k10 site to a integration environment and are facing the problem, that on the target environment nodes in tree views in all cms sections are not expanding. The console shows a 400 error (Bad Request).

First we checked the axd handlers in IIS. The configuration here is the same as on the development environment, where everything works fine.

IIS Version is 8.5 on both systems.

We are out of good ideas how to fix this and therefore help is very welcome!

Thanks and regards from switzerland, Bernhard

Here's some things to check.

  1. Event log, are there any errors?
  2. Have you tried doing a System > Macros > Signatures and resign old macros?
  3. Using your browser inspector, are there any javascript errors?
  4. Which URL call is giving a 400 error? Perhaps there is a missing file?

Check the above, and post back, hopefully we can figure it out!

  1. Event log shows no errors when trying to expand a node.
  2. Signatures have been updated without any effect on the problem.
  3. The console shows no JS-Errors - just the 400-Error
  4. As far as i see there is no file request performed to a non existing file


Any furhter help is highly appreciated :-).

Best, Bernhard

Okay, based on the screen shot, IIS is giving it's default 400 error path for the request (/error_path/400.html)

The first request on your screenshot (Default.aspx) is the call to the CMSMOdules/Content/CMSDesk/Default.aspx, THIS is the ajax postback for the response in question and since it shows 303, this may be what's wrong (Normally shows 200)

If you can provide it's Headers and Response here, that should help us further! It may be returning an error that we can use to get closer to the solution.
