When I attempt to upgrade my wordpress site to the latest version (3.3.2) thru the auto update in the dashboard it goes thru the process and at the end says there is an error when the site goes into maintenance mode. When I reverse all the changes and look for the maintenance file to delete I can't locate it at all.
I then try to do a manual update and I then get a blank screen when attempting to log into the back end of the site. I also disable all plugins before I attempt to upload updated files.
Any suggestions as to what might be wrong?
