I'm having a problem upgrading. I downloaded the 2.2.1 zip file from the server and uploaded it to my site with Filezilla (the same way I have my original installations and all my upgrades).
However, the plugins page still says I have version 2.1.8 installed. I tried deactivating the old install before the upload... same result.
So I deactivated and deleted the akismet folder from my plugins, and then reloaded the page to be sure. Akismet was gone from the plugins list as expected. But when I pushed the 2.2.1 folder back up again, it still shows up as version 2.1.8! I saw the message about clearing your internet cache, I tried that... same results. I tried logging into my website with Internet Explorer instead of Firefox, same result. I tried downloading the zip file again to be sure I had the right version... same result. Is the 2.2.1 link on WP plugins pointing to the wrong file or am I doing something else wrong?
