I want to access my sitecore client. I access on mywebsite/sitecore/login. Then I click on the Launchpad, there exist error like this :
[![enter image description here]]
I try to rename ```001.Sitecore.Speak.Important.config.disabled``` to ```001.Sitecore.Speak.Important.config``` for enable it, but it does not work. It makes the server an error
How can I solve the error?
