Error: PHP Tags

I just moved a site of mine to another server where I get this error:
"H:i', 'date-format' => 'd.m.Y' ); /* unset default if setting already set */ foreach ( $default_settings as $key => $value ) if ( op_get_setting( $key ) ) unset( $default_settings[ $key ] ); /* apply remaining settings */ $wp_opening_hours = new OpeningHours; $wp_opening_hours->applySettings( $default_settings ); } register_activation_hook( __FILE__, 'op_activate' ); ?>"

The new server can’t handle <? instead of <?php, I just tested it with another piece of code, so I guess that’s where the error comes from.

Just wanted to let you know.
