I upgraded today. Manager disappeared. Re-installed Manager. I see and click on the icon. There is no reaction at all. Using Ubuntu 14.04. The “Your topic is similar to…” is not similar.
I then uninstalled and installed from Manager site. Now clicking on the Manager icon I get this message.
System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at System.Collections.Generic.Dictionary`2[System.Guid,System.Type].get_Item (Guid key) [0x00000] in <filename unknown>:0 at ManagerServer.Serialization.GetTypeByGuid (Guid guid) [0x00000] in <filename unknown>:0 at ManagerServer.Objects.Get (Guid entityId) [0x00000] in <filename unknown>:0
