I do not know what it was. At 3 o'clock in the morning, I was very sleepy, but wanted done one template. I have worked with templated screen, adds, removed somethings, but only in this one template.

At some point I noticed that I can not add graphics from the template that I made yesterday. And then more - I noticed that in general there is no graphs in any templates or at the hosts.
Watching the database - and indeed the tables 'graphs', 'graphs_items' is empty.

I was thrown into a fever and I abruptly woke up
While I can not reproduce this problem, but it definitely came out of my usual work in the web interface. I am the only user.

I decided to write it so that you know and continue to try to reproduce my steps ...

One question - I had a DB backup? Answer - thank god, yyeeeesssss !!!
