Chrome - cross-origin frame error

[learnedbyerror]

All,

Starting sometime yesterday, I started having problems with not being able to see the details for a specific Container/VM in the PVE web interface. The steps to reproduce are:

1. Using Chrome, login to PVE Web Interface
2. In the tree control on the left, open the Proxmox physical server to view list of Containers/VMs.
3. Click on any Container/VM
4. The panel on the right is gray - no content.

When I enable the Chrome Developers tool, I see the following cross-origin frame error.



This error is repeatable in Chrome Version 64.0.3282.167 (Official Build) (64-bit) on the Mac and Version 64.0.3282.167 (Official Build) (64-bit) on Windows 10.

The screen works fine on Safari on the Mac and in Firefox both on Mac and Windows 10.

I performed an apt-get update and apt-get dist-upgrade this morning thinking that new patches may solve the problems but it did not.

Is anyone else seeing this problem?

Sorry for the late response, yes, the problem was the cVim extension. I missed your response and didn't put 2+2 together until just now. I disabled cVim probably a week after the post because I wasn't using it. A little later I realized that proxmox was working again.

Thanks for your response!
