I’m on 6.3.7, trying to Install 6.4 on my MacBook Pro running OS Sierra 10.12.1
Everything downloads fine from the Search for Updates menu, and extracts automatically. But then I keep getting this message:
What can I do?
Also I’m really not sure if my sites are publishing properly - I make changes which appear to upload OK when I hit ‘Publish’ but then when I check them online they appear the same as before. I’ve tried emptying caches/different browsers to no avail. Any suggestions?
