I just had this same issue last night. I’m running WordPress 3.6.1. I installed Yoast. My website was working fine. I set up Yoast settings … everything seemed fine. Then this morning I checked my website to find it was showing an Internal 500 error for all public pages.
My site is installed in a subdirectory (/site/) but viewable in the root directory http://www.duoplus.co.nz (this works fine). But when the Internal 500 errors were happening, I could still get to the admin pages (which are still located in the /site/ directory). In the settings page I changed my site back to pointing at the /site/ directory and it immediately started working again. This raised my suspicions about the .htaccess file. Sure enough, for some reason it had reverted to the earlier edition (which doesn’t point at the subdirectory location).
To fix it I copied the .htaccess file from /site/ to root again. Change the site’s URL back to root, and it started working again. All my Yoast settings were wiped which was another weird thing.
So I’m not sure if Yoast was to blame, or something at my host. But everything was working fine last night, and Yoast was the only structural change I made. It’s working again now. Hopefully permanently!
Not sure if this helps, but I suggest looking at your .htaccess file.
Yes, same issue
after update to 1.4.18, filling my server disk with gigs of error in apache error log ( in few seconds ) :

I roll back to the Yoast SEO 1.4.15 and everything is ok now.

Yes, same here.
I just updated to the new version & got 404 errors on most pages. I’ve deactivated the plugin & my site is all back to normal now.
The .htaccess file has the following, I’m not seeing any obvious problems. Any ideas?
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>
# END WordPress
After looking at my server logs:
/web/wp-content/plugins/.htaccess: AuthName takes one argument, The authentication realm (e.g. “Members Only”)
I found out that yoast installed a .htaccess file inside of my plugins folder. After deleting this file (wp-content/plugins/.htaccess), everything worked fine and the 500 internal server error disappeared.
