COOKIEPATH equates to ‘home’ and SITECOOKIEPATH equates to ‘siteurl.’

I was initially wrong about it possibly setting two cookies.

What’s happening is, it will set a test cookie with path based on the url found in ‘home.’ If ‘siteurl’ and ‘home’ are different, it then rewrites the test cookie with using the path based on ‘siteurl.’

Either way, you should get a cookie.

The test cookie is set by wp-login.php, and like you, when I go to the login page on your site, no test cookies are set. I also noticed that the wp-admin and colors-fresh css are not loading.

Never the less, wp-login.php should set the test cookies, nothing special there and nothing regarding that has changed with WordPress 3.7.1 that I’m aware of. So to me it looks like that wp-login.php is the culprit.

Can you verify that:

setcookie(TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN);
if ( SITECOOKIEPATH != COOKIEPATH )
	setcookie(TEST_COOKIE, 'WP Cookie check', 0, SITECOOKIEPATH, COOKIE_DOMAIN);

is in your wp-login.php file?

WordPress will set one or two test cookies when you go to wp-login.php. If siteurl and home are the same, then just one cookie. So after you go to wp-login.php, check if you have any cookies named ‘wordpress_test_cookie.’

You can check your siteurl and home url via SQL. In my case, for example:

mysql> SELECT option_value FROM wp_options WHERE option_name='home';
+------------------+
| option_value     |
+------------------+
| http://localhost |
+------------------+
1 row in set (0.00 sec)

mysql> SELECT option_value FROM wp_options WHERE option_name='siteurl';
+------------------+
| option_value     |
+------------------+
| http://localhost |
+------------------+
1 row in set (0.00 sec)

So since siteurl and home are the same, I only have one test cookie set.

Name: wordpress_test_cookie
Content: WP+Cookie+check
Host: localhost
Path: /
Send For: Any type of connection
Expires: At end of session

Upon login, WordPress checks that the test cookie has been set and you’ll get that error if not (assuming the form is sending the hidden param of testcookie=1, which it should)

So first see if wp-login.php (just go to the page, you don’t need to login) is setting the test cookie(s) for siteurl and home.

3.7 auto updates only do minor point release updates (security/bug fixes, like 3.7 -> 3.7.1). If you see “Database Update Required” then it’s likely your host is updating WordPress for you, as that suggests a bigger change. I don’t believe you should ever see “Database Update Required” for a minor point release update. I leave 3.7 auto-updates enabled for my sites, but do major updates (say 3.6.x -> 3.7) manually after testing plugin/theme compatibility on a staging site.

Yes, it is premium, and I know that doesn’t suit everybody (though the license is only $5). I only offered that link because I don’t know of any free alternatives that works.

If it’s set to permission of 404, then there’s no way your .htaccess file could be overwritten at all unless something is changing the file permissions first.

Looks like your WordPress update didn’t complete or was corrupted. Your best bet would be to reinstall WordPress. You could try uploading /wp-includes from a copy of WordPress 3.7.

I’m not sure what you mean by you deleted everything dated today an yesterday, but from the error message, there is at least one file missing (/wpincludes/pomo/mo.php).
