Problems with notice I'm new in Drupal. I had to migrate a page from a client to another server. The page work well on a development test but not anymore.

I have these errors:

Notice: Undefined index: highlighted en include() (línea 126 de /home/portal/public_html/modules/system/page.tpl.php).
Notice: Undefined index: sidebar_first en include() (línea 138 de /home/portal/public_html/modules/system/page.tpl.php).
Notice: Undefined index: sidebar_second en include() (línea 144 de /home/portal/public_html/modules/system/page.tpl.php).
Notice: Undefined index: hotel en drupal_theme_initialize() (línea 100 de /home/portal/public_html/includes/theme.inc).

The link to the page is: http://www.portaldelcuadrado.com.ar/
What can i do?

Thanks
Is the theme on the test site and the live site the same theme with the same regions defined. The drupal theme() function is complaining that regions are not defined which the body (node) content is trying to be placed in.
