Hi Howard. Thanks a lot for getting back to me. So this is the exact message I get whenever I get this error: 500 Server Error
A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again.
URL: http://www.dentistcudahyca.com/wp-admin/plugins.php?deactivate=true&plugin_status=all&paged=1&s=
and then this is what I get in my error log:
plugins/wordpress-seo/inc/wpseo-functions.php on line 344
I hope that is what you were asking me.
