Problems after template saving error

Hi everyone!
I had strange problem: while saving changes in template modX had an error:

An error occurred while saving the template.

template_err_save in lexicon (i'm using ru-instace of modX).
Then i had a strange message on my indexpage of site:

In backend tree of pages i cant find a Home page (w/ id1), but another page chnged id to 1 and waas first in tree.
In errorlog of modX:

[2012-08-31 01:30:25] (ERROR @ /connectors/element/template.php) Произошла ошибка при сохранении шаблона.Array
[2012-08-31 01:30:54] (ERROR @ /manager/index.php) Произошла ошибка при сохранении шаблона.Array
[2012-08-31 01:49:42] (ERROR @ /index.php) template_err_saveArray

Log management system does not contain any records except to save a template (by me).

What happined and how can i repair my site?

Thnx and please sorry me for my ugly english
