Problem with the body field after upgrading to 7.7

Question

I recently upgraded to 7.7 because of the security updates, but now, when I try to add content there is no body field... and when I go check the module list I see this message on top of the list.

Notice: Undefined index: module in _field_info_prepare_instance_widget() (line 382 of /var/www/gisele-drupal/modules/field/field.info.inc).
Notice: Undefined index: module in _field_info_prepare_instance_display() (line 350 of /var/www/gisele-drupal/modules/field/field.info.inc).
Notice: Undefined index: module in _field_info_prepare_instance_widget() (line 382 of /var/www/gisele-drupal/modules/field/field.info.inc).

Does anyone know what could be going on here, and how can I solve this?

Answer 1

Are you using OG? Because that could be causing the issue.

Things to do

1. If OG is installed, but not enabled delete it.
2. Clear Cache
3. Update all modules up to their most recent versions
4. Run Update.php (do whenever a module is updated or deleted)
5. Uninstall Views and reinstall it

Besides the core issue, there is also a problem with Entity Reference: http://drupal.org/node/1329354. I'd recommend doing some disabling (as suggested) to determine which of these bugs is the culprit.
