For some reason, this problem is only happening with Chrome. It was just my home computer for a while, but today it's also a problem on my work computer. I've deleted the cache, the cookies, the browsing history, even my saved passwords, and nothing helps. I've uninstalled and reinstalled all plugins one by one, and tried a clean install of WP. My blog is in a subdirectory of my website (mysite.com/blog) and both the WP address and site address are that. The blog itself isn't having problems and shows up to my readers just fine.
The issue is that when I try to go to my admin login page, (mysite.com/blog/wp-admin), it redirects to http://mysite.com/blog/wp-login.php?redirect_to=http%3A%2F%2Fmysite.com%2Fblog%2Fwp-admin%2F&reauth=1 and I am unable to login. It's like pressing the button does nothing, because the page doesn't even show that it's loading. I also can't click on the "Remember Me" check box. The URL redirect is happening on all other browsers I've tried (Firefox, IE9, Opera, Safari), but I am able to login still on the other browsers (for now).
I know the easy solution is to just use Firefox instead, but I'm afraid that I soon won't be able to login using that either. I haven't installed any plugins recently, though I did delete the W3 Total Cache plugin (as it was giving me other problems a few weeks ago) recently. I haven't changed any settings since yesterday (this issue wasn't happening then), and I have already contacted my hosting provider and it's not an issue on their end.
the link to the page that's having issues, if it helps, is kristibeck.com/blog/wp-admin
