WordPress - Fixing “Your connection is not private” issue with Chrome v44

THIS ARTICLE WAS WRITTEN REGARDING A BUG IN CHROME AND THE ISSUE WAS FIXED A LONG TIME AGO.

TO FIX “Your connection is not private / secure" issue in Chrome / FireFox" PLEASE CHECK THE FOLLOWING ARTICLE: http://bgroot-eng.blogspot.bg/2016/08/fixing-your-connection-is-not-private.html

Update 1: The issue should be fixed in the last Chrome update (Version 44.0.2403.107 m)

It appears that in the Chrome 44 release (version 44.0.2403.89), that happened just yesterday, Google made one little change that affects many websites and not for good.

It's now sending the 'HTTPS:1' header on every request by default. This affects many websites (core and plugins) and mainly some WordPress Plugins. This should be a change for a good, to enhance security but it seems that a lot of the developers were not ready for that change.

In general if you are not using SSL certificate for your website and try to access the admin section of your WordPress site (domain.com/wp-admin) it will redirect you to the https version of the website and you will get the error that “Your connection is not private” and “ERR_CERT_COMMON_NAME_INVALID “.

Some of the plugin developers already released updates which will fix this bug. However a lot of them still haven't.

Here is the solution of the issue if you are using Wordpress CMS:

1) Update all of your plugins! (use different browser to access your wp-admin section) In most of the cases this will fix the issue.

2) Purge your cache if you are using any cache plugin.

3) Check if you can access your admin section via Chrome!
If it's fixed, you don't need to do anything else. If the issue was not fixed move to the next step!

4) I work for a hosting company optimized for a fast WordPress moneymaking websites. Our team have created one miniPlugin for WP which fixes this issue. You can download it from here:

https://trafficplanethosting.com/downloads/category/2/fixes/

Install the plugin from the  Plugins section in your WP website:

Plugins > Add New > Upload Plugin > upload the ZIP you have already downloaded > Activate it.

When the plugin is active you should see a notice in the top of the page: “The fix for Chrome v44 is active now. Thank you for using Traffic Planet Hosting”. If you do not want to see this anymore you can click on “Close” and it will hide it for your user.

5) Check if you can access your admin section via Chrome!

You can remove the plugin when all of the plugin developers release fixes for their plugins.
