By 'reloading the plugin' do you mean you've clicked the 'Reload all plug-ins' button on 'Plugins' page in vCO Web configurator?
On 'Troubleshooting' page, there is a link 'Reset current version'. Did you try it? Supposedly, it will re-install the plug-ins on the next server restart.
Manually adding the package 'may' work, but is not supported - package should be deployed as part of plug-in installation.
What errors do you receive when trying to log in? Could you check the vCO log files for exception/error stack trace?
Using the "Reset current version" button fixed the issue.
Thank you very much.
I've followed your instruction but still have same issue.
I'm using vCO appliance.
The only error message I've got is: "The webview 'weboperator' is not published."
Any suggestions how to resolve it ?
I've just pressed the reset current version button than I reloaded the plugins and that fixed the issue for me if I remember correctly. I am not using the appliance though so it might be a different issue
