error ZaOverviewPanelController.prototype._overviewTreeL istener

[nora]

Hi

I've Install zextras 3.0.3 on a zimbra 8.6.0 and when I select the "core" section, the following error will appear "A JavaScript error was detected in the ZaOverviewPanelController.prototype._overviewTreeL istener method" how can I fix it?

Thanks

Hello Nora,

if this is an upgrade you should really try to clean the cache, both the server's (with "zmprov fc all") and the browser's (or try with another browser).
Is any exception logged in /opt/zimbra/log/mailbox.log when the admin interface returns the error?
