I don't speak good english, sorry.
I want to translate my Sleek Theme.
I tried to make it going here but in all translation topics i read

Marinski, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

The question is... Why?
Simple answers without smart text like sms, thank you!
