ehsh01 on "IDrive on Synology DSM 6.0 Beta"

Hello there, I am using DS1515+, I did the upgrade in the following order.

1. Upgraded to DSM 6.0,
2. iDrive stopped working.
3. I downloaded and installed latest version 2.03.19.
4. Got 404 error message.
5. Then I followed the steps to enable read/write permissions for "http" in local groups under the "shared folder web" permissions.
6. So now when I click on iDrive I still get the "404 the page you're looking for cannot be found" message.
7. What else can I do?

Thank you all for all the hard work you're putting in to fix the issue.
