Wordpress question
 

So I got the notice to upgrade to the newest version of wordpress today. I backed up my databases and proceeded to upgrade. Afterward, the page redirected to a 404 at [mydomain]/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F which I continue to get when I log in. Other than that, the site appears completely functional.

My question is this: can this be undone simply by reinstalling wordpress, or will doing that mess up my plugins and stuff?

Alternatively, if someone has additional insight into what has happened/is happening and provide any info on how to fix it, it would be much appreciated.

Uninstall your plugins and see if the problem persists.

I had the same 404 problem with posts. Changing permalinks to DEFAULT then changing it back fixed the problem.

manually upgrade again just write over the files it should work theme files will remain untouched unless you used twentyten or one of those ones

Thanks for the advice - I'm going to have a go at fixing it tomorrow.

What cheeses me off is I just fixed a snafu caused by a plugin update. I've given some thought to just ignoring future updates altogether once I get everything working the way it should.

i always just disable plugins and problem solved

reenable one by one until you identify the trouble maker

goto site.com/wp-admin

Make sure the new install sent stuff to the right folder.
