Upgrading Drupal

Hi,

I am getting this this notice after successfull D6 to D7 upgradation.

"Notice: Undefined index: entity type in views_handler_field_entity->init() (line 38 of /views/handlers/views_handler_field_entity.inc)."

How to remove this notice.

Thanks

Hi,
I've just been handed a site that has been constructed in Drupal and I have never used Drupal before although I have done website development. I do not know what version although there are warnings that upgrades are required.

Reading through the documentation it looks like the original developer could have made several difference choices as to how they developed the site. Is there a quick and easy way to look at how the site was originally developed and what database was used?

I upgraded from Drupal 7.1.0 to Drupal 7.1.5, and my php functionality is having trouble. To be specific, I use an external php to construct data from the Drupal DB and pass it as a json object that is loaded on the page initialization (using sAjaxSource in datatables). At the start of the php file, I have following lines:

define('DRUPAL_ROOT','../../../../../drupal');
include DRUPAL_ROOT.'/includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

While updating Ubercart in a Drupal 7 implementation for the website, www.tixwriteoff.com, I can't log in as admin. It also crashes the site. I am locked out and can't make any further changes or rollback.

Clearing the cache allows me to use the website as a casual internet person. An attempt to log in as any type of user (admin or customer) kills the website and shows the following message, "The website encountered an unexpected error. Please try again later."

Hello,
I have upgraded a portal from D6 to D7. I see the message comes on my screen to rebuild content access permission but when ever I am trying to do that, I am getting a error like this after some time of process -
An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /connect/batch?id=156&op=do StatusText: error ResponseText: EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 7562 of C:\LocalServer\xampp\htdocs\connect\includes\common.inc).

Is there a way to use Backup and Migrate to migrate the content of an old Drupal 5.x
site to a new Drupal 7.x site?

I've been able to create a backup on my 5.1 site using the 5.x version of Backup,
but when I then try to "import" that data to my Drupal 7.x site, I get errors.

Is it possible to do this at all?
