    Hey WordPress developers,

    I don’t know what you’ve done but every upgrade comes with troubles. And this is annoying me.

    In this case: all my websites are extremely slow, it’s hard to load dashboard, update plugins, etc.

    I’ve checked with Pingdom, Google’s Pagespeed, and GTMetrix and saw that especially WP-ADMIN is causing the problems….

    It’s loading weird stuff like icons, emoji’s and other external stuff that comes from…… PS.W.ORG. Also the update makes all my sites (5) very slow. It takes almost more than 30 seconds to load a page and dashboard.

    Also there are problems with wp-includes, and jquery’s,

    The problems started after update to 4.6.1…..
    It looks WP is very unstable!

    Have you tried:

    – deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

    – switching to the default theme to rule out any theme-specific problems.

    – resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

    – re-uploading all files & folders – except the wp-content folder and wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    1. Before I did the update I’ve switched off all plugins. Delete cache, Cloudflare, etc.

    2. I did the manual install.

    After update I’ve reactivated plugins one by one and did some performance tests but performance is very horrible.

    The problems are caused by . wp-admin/admin-ajax.php

    also according to Pingdom, GT Metrix and Google Pagespeed problems with wp-includes and especially the jquery’s are causing problems.

    WP-ADMIN and WP-INCLUDES come with the updates; it’s replacing the old wp-admin and wp-includes.

    Hint:
    the problems started after update to WP 4.6.1. Something went wrong in coding.

    Additional info

    Before WP 4.6.1. (a couple of months ago) all my websites (5) were blazing fast!
    Now my websites almost need 40 seconds to load. Not just one website but all five!
    This is an indication of a structural problem.

    I’ve Googled on wp-admin.php and I’m not the only one facing this problem.

    Please try switching the theme and resetting the plugins folder. This could be a theme and/or plugin issue. There are currently no known performance issues with WordPress itself – although you may have a hosting problem.

    how do I reset plugins folder?

    Instructions please.

    Also did updates with Theme Twentyseven.. still same problems.

    Note:
    Problems happened after update. Not after Fresh install!

    I’ve created a test-website with a fresh wordpress install and this went smoothly.
    I guess some bad residues are left behind in database or somewhere else after update.

    I’ve found the problem with my sites after updating: it’s caused by W3 Total Cache. It acts weird when WordPress is doing the (Auto-)update. So you need to remove it completely… before (!) the update.

    Wordpress auto-update made my life miserable because it didn’t deleted W3 Total Cache completely. W3 Total Cache keeps “working” after you deleted it from Admin Dashboard; not all files are removed.

    Instructions:
    1. Make sure Wp Auto-update is switched-off:
    Go to your wp-config.php file in cpanel or FTP and paste this code:

    define( 'WP_AUTO_UPDATE_CORE', false );

    2. Remove the following W3 Total Cache files manually.
    Read the instructions here:

    After I fully deleted all W3-Total Cache related files, all my sites were back on A 98% according to Pingdom, GTMetrix,etc.
