Upgrade to 3.8.1 has resulted in inability to maintain site, pages, or posts

Since upgrading I have had an impossible time using wordpress. My dashboard is coming up as a list instead of a user friendly interface, I cannot add to or add pages or posts. I get the following error-
Connection lost. Saving has been disabled until you’re reconnected. We’re backing up this post in your browser, just in case.

I have disabled all plugins and this does not work. I have tried to reinstall but I get a fatal error
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1194152 bytes) in /home/ajfitzer/public_html/wp-admin/update-core.php on line 150

I am losing money and time. My business is suffering and I cannot offer my programs or information to the general public while this is going on.

Help me please. I am not a programmer but play one on wordpress ??
