Hey everyone,

I'm running into persistent 405 Method Not Allowed errors when trying to delete or save content using the 2sxc module on DNN v10.00.01 with 2sxc v19.03.05.

Hosting Environment:

IIS 10 (self-hosted)
DNN 10.00.01
2sxc App with content editing on multiple pages (blogs/services)

Issue:

Whenever I try to delete content or save certain edits in 2sxc, I get the following error:

azmanagedit.com says: Had an error talking to the server (status 405).Issue:Issue:

Resolved 2sxc 405 errors on delete/save actions in DNN 10 by disabling the 'WebDAV Authoring Rules' feature in IIS.

Remove via Server Manager

Open Server Manager.
Go to Manage → Remove Roles and Features.
Click Next until you reach Features.
Uncheck WebDAV Publishing under Web Server (IIS) > Web Server > Common HTTP Features.
Click Next, then Remove.
Restart IIS:
