@Diegothanks for your reply!!

I answer your questions below:

* Confluence 7.4.4
* Windows 7 64 bits
* I would like to migrate from Cloud to Confluence server, but the thing is that I can't star the server before the Cloud import.

Before our answer, I was thinking that the problem could be that I don't have the required permissions to start running the server... is it a possible cause?

Thanks!!

Hello @Manuel Calderón !

This error could be related to the order in which your user directories are currently set. More specifically, how they are listed in your database. Usually means that no directory with the index of 0 exists.

You can check more details about it here:

* [Confluence Server] Confluence returns system error due to 'Invocation of method 'isShowSignUp' in class com.atlassian.confluence.user.actions.LoginAction threw exception java.lang.NullPointerException at /login.vm'

Even though we have this document about the issue, I would like to ask you a few questions:

* What version of Confluence are you currently running?
* What is the operating system of your server?
* Was Confluence working before the Cloud import?

Let us hear from you!
