I've successfull update a magento from 1.7.2 to 1.9.2 and all work fine. Then I've upgrade the theme and now not working fine, in homepage the error is:
CRIT (2): Not valid template file: frontend/base/default/template/page/1column-wide.phtml
Really this file exist in installation, but there is in another directory,
I think that in DB or in some file there is a referement at this path, and with update magento this not working yet.
