Our site today had to be moved to a new server. Our site admin copied the files over to the new server and absolute mayhem as broken out. The site is here, if you can get into it at all. There are millions of errors all over the place with messages such as:
Notice: get_settings is deprecated since version 2.1! Use get_option() instead. in /usr/home/medi51/www/htdocs/report/wp-includes/functions.php on line 3237
Fatal error: Call to undefined function the_advanced_excerpt() in /usr/home/medi51/www/htdocs/report/wp-content/themes/cyspy/index.php on line 37
__ngettext is deprecated since version 2.8! Use _n() instead. in /usr/home/medi51/www/htdocs/report/wp-includes/functions.php on line 3237
Most of the site doesn't load at all. We did a straight copy of our installation: nothing was changed. All plugins were fully updated and fully functional prior to the move. Any idea of how to diagnose and fix?
