I'm using a Mac with Safari 3.2.1 or Firefox 3.0.7.
I've had my blog since WordPress 1.5, and never had problems with logins previously.
Over the weekend, I upgraded php from 4.3 to 5 on my host site. I also did some plugin tweaking, but I don't think either of those things necessarily did anything to break my site.
I can log in fine using either of my admin passwords. The whole time I'm on the admin pages I stay logged in. But if I navigate back out to the homepage, I'm no longer logged in.
As a result, if I schedule a post, and then click "view post" to make sure I didn't screw up the image url, I can't see it because we're not in the scheduled time yet.
Already tried clearing cookies on both browsers, and resetting both browsers, with no effect. I also replaced my wp-config.php file with the latest wp-config-sample.php file (with all my values, obviously) since I hadn't added the newer security fields yet. I even tried rerunning "wp-admin/upgrade.php" to see if maybe there was something that had to re-something because I upgraded php last weekend, but it had no effect.
Is anyone else having trouble staying logged in on their main site?
One other note - I also have an install to bbpress on this site, and I use wpstats, but I don't think either of them is corrupting my cookies, because if that was happening I wouldn't be able to stay logged in on the admin site either.
thanks in advance!
