Virtualmin SVN Repo and webDAV issue while using repos

Yesterday i read about installing and configuring svn repos with virtualmin and i did it via Virtualmin > Fetaures and Plugins.

Then i created a user and provided privilges to the user to access the repo. Now i have added the repo to a client interface and while creating a folder i am getting the following error:

Create ‘Create Folder’ folder failed.
svn: E175003: The OPTIONS request did not include the requested activity-collection-set; this often means that the URL is not WebDAV-enabled

Assuming a bit and reading about DAV service on the web i have also installed the DAV login plugin and enabled it for the domain as well as for the user.

And i still get that error.

Please help me proceed and resolve this issue … i have searched a lot and still not able to find the exact solution
