When i try to replace an image on a page I get this error. Frankly, I don’t understand the reply on how to correct it. Why is swapping out an image causing a critical error?

Error has changed after selecting and attempting to delete duplicates.

Response from the server: Unknown error occurred

Still there. Fully updated.

Also still getting same error.

Unfortunately, I’m having the same issue (can’t delete or edit redirects). What was causing the problem?
