Lots of bugs with the latest WP update

Hi everyone,

I just updated to the latest version of WP yesterday, and ever since I’ve been having all kinds of issues.

Whenever I go to save a draft for later, it always says the operation has failed. Also, I am constantly booted out of my sessions and forced to log back in. I’ve also noticed on the site that pages will come up as not found, and category and archive lists will disappear every now and then.

Is anybody else having these issues? Is there anyway I can downgrade and go back to the previous edition of WP?
