 * This is what I’m getting after upgrading WP to 4.3.1. I can’t log into the site,
   can’t do anything except through cPanel, and I’m not well-versed enough in PHP
   to fix this. I’ve tried the ‘deactivate plugins’ route and nothing. Cleared my
   browser cache. Nothing.
 * ***
    Fatal error: Cannot redeclare the_replacing() (previously declared in /home4/
   wolfeang/public_html/citykittycreative.com/wp-includes/query.php:836) in /home4/
   wolfeang/public_html/citykittycreative.com/wp-includes/query.php on line 837
 * ***
    Any help would be appreciated.

 * if you’re in the panel then rename your plugins folder to something else (i usually
   just stick a random letter on the end of it…) and then head back to your site.
 * when you upgraded to 4.3.1 did you upgrade from a much lower version? did you
   follow the wordpress guide to upgrading or just click the big shiny button?

 * Did that before and no, it didn’t work. Just tried it again, just for the heck
   of it, and nope, still won’t work.
 * As for my upgrades, I’ve kept up on them and it was a small upgrade.

 * back up your site!! download a copy of wordpress and then try uploading and overwriting
   your includes folder, you may have a corrupted file in there somewhere… but back
   up the site before you do it! 😀
