Password protecting my pages no longer works with 3.8 upgrade on a very simple site with very few plugins activated. The only one that was active was Akismet. The page simply says protected and does not provide field to enter in password and all content is visible. I updated my theme, no issues there. I tried another 3rd party plugin in handle password protected pages, that doesn't work either. There appears to be an issue reported that since 3.4 WP doesn't use /wp-pass.php anymore and to replace this with another path but I can't find this code anywhere.
Suggestions? I'm getting somewhat annoyed with word Press changing things to "improve" - every upgrade just seems to breaks the simplest of sites.
