Description
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?

Looks like an issue with WordPress to me - everything was working perfectly fine until i upgraded to 4.6 and did the database upgrade. I upgraded 7 sites and they are all giving me these errors. I reinstalled WordPress on one of the sites and its working fine now - its definitely an issue with WordPress - or the database upgrade process.

With a topic in the support forums we could more easily help you and open a trac ticket if necessary.
When you open the developer console in your browser (F12), you should be able to see the Ajax requests triggered when deleting or installing a plugin/theme. If you could share the responses of those, this would be helpful.
I assume there are some PHP notices or errors being thrown which cause the process to fail.

Ok here's one example - i just tried to delete one of my child themes and here is the WordPress error i got along with the ajax return message in the web console:
WordPress error:
Deletion failed: The requested theme does not exist.
Ajax message:
{"success":false,"data":{"delete":"theme","slug":"hope-charity-theme-child","errorMessage":"The requested theme does not exist."}}
The theme is installed and i can verify its installed through FTP - but for some reason WordPress thinks it doesn't exist.

Might be related to #37924.

If i understand correctly that article mentions that the error is related to uppercase characters in the directory name? My theme does not contain uppercase characters in the main theme folder which is labelled "hope-charity-theme-child"
Sorry but i don't believe that article resolves anything.
Hi,
It appears to be an issue with your WordPress installation or your server, not an issue with WordPress. With that being said, it should be a support ticket and you should open one here with all the details: https://wordpress.org/support/
