Errors Saving Entries Suddenly getting errors when trying to save entries.
Have recently upgraded to latest version of Craft.

When I try up update a Single Entry I get the error:

Fatal error: Call to a member function getAttributes() on a non-object in /path-to-site/craft/app/controllers/EntriesController.php on line 484


When a try to save a Channel in IE11 it pops up - Do you want to open or save - 210-a-new-news-articlef93bf125.json(1.09KB) from domainname.com

What is causing this problem?
Sounds like something may be corrupt in your /app folder... I'd recommend performing a manual update to try to fix the problem.

If you are still experiencing this issue after performing the manual update, I'd recommend contacting Pixel &amp; Tonic directly, to report this as a bug.

You can email them at support@buildwithcraft.com, or use the "Send a message to Craft Support" widget on your dashboard.
