Bug after update 4.022 to 4.023

[mtb2000]

After updating from 4.0.22 to 4.023 the items, and discovery page of a host are blank,
Configuration->hosts -> click "items" from a host -> blank screen..

I allready restored my Zabbix server to a previous version, but bug returned after an auto update.
Any one knows the fix?
