 Hi,

 I am facing several errors in the backend after upgrading to WordPress
 version 4.6

 For example when i try to delete a theme i get the following error
 outlined in a red notification box:

 '''Deletion failed: undefined'''

 When i try to update a plugin i get the following error:

 '''Update Failed: Internal Server Error'''


 Is there a quick fix for this?
