[2014-11-25 08:06:40] Espo.ERROR: Uncaught exception {"exception":"[object] (PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user.name' in 'field list' at /var/www/crm.vmclouds.ru/application/Espo/ORM/DB/Mapper.php:132)"} []

To fix it, go to /custom/Espo/Custom and name "Resources" directory to something like "Resources-old" or just remove it if you don't have any other customization. After that, go to /data/cache and remove "application" directory. Now, it should work.
Thanks. It will be fixed in a new release.

Can also happen if the system user account is deleted. To prevent accidental deletion in MySQL use this trigger:

CREATE TRIGGER `protectsystemaccountbeforedelete` BEFORE DELETE ON `user`
FOR EACH ROW BEGIN

IF (OLD.id = 'system')
THEN
SIGNAL SQLSTATE '45000' set message_text='Operation Disabled!';
END IF;

END
