laverna.cc does not open

[motingo]

I have been using laverna notes web without problems during more than a year.
But since 5 or 6 months ago i can not open laverna.cc site as i used to.
When i click this site: https://laverna.github.io/static-laverna/, it opens the usual page of laverna but without my notes, all blank
I can not access my notes anymore.
Unfortunately i did not make a back up in dropbox for the last notes.
What can i do to recover them?
Hope you can help me.
Thanks a lot
