I have been upgrading Drupal core from 7.32 to 7.38 version and it was giving me the below error:
EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 7836 of xxx\includes\common.inc).
Solution : So I replaced the latest Drupal 7.38 includes/entity.inc
with Drupal 7.32 includes/entity.inc
and that solved the issue.
Also here are the steps I followed:
1) Upgraded the Contributed Modules
2) Upgraded theme
3) Upgraded Drupal Core
5) Ran Update
6) Replaced includes/entity.inc as mentioned in the solution.
and I am all set.
Although I have been hearing there is some issue related to Drupal 7.38 includes/entity.inc. But I am comparing it further to identify the changes related to it which is causing the core file to act as an issue. I will share my findings after going through the same.
