   This article is a little bit trap for newbie because if you first change to https in your wp panel and then try to add those codelines to right files you can’t reach your webiste or wp admin panel. (443 error) I had to edit files through ftp and made myself fool at work for making such a mistake. So first you have to get the certificates and edit htaccess file etcetc and then add that S in your wp admin panel (or directly edit thorugh ftp).

   Hi! Thank you for this article. Very useful!

   But I was faced with one problem. After installing SSL (I use free version of Cloudflare SSL) I cannot edit any pages/posts/products. Does anybody face with such problem? And how did you solve it?

   Thanks in advance!

   Hello There,

   Wonderful article. The issue I have with using the .htaccess file to route through https is that whenever WordPress updates, it cleans off the edits done.

   Is there a way to avoid this?

   Hello,

   I’ve purchased an SSL certificate form Godaddy and it is approved and downloaded the .crt file. I’m bit confused what are the next steps to install the file in the server and how to redirect all the URLs in the existing WordPress site. Can anyone give me the detailed guide step by step.

   Also requesting WPBeginer to write an article on this topic “How to install SSL certificate in Godaddy.

    • Karl D.

      Don’t know if you got this fixed, but you can go into mysql (phpMyAdmin) and look for the table wp-options. There you will find a table entry titled “siteurl” and one titled “home” you can remove the s from https in the url there and your site will come back. I would make sure that you have the .htaccess and wp-config edited like stated in this article first and upload them to your site first and check if things work from there. If not, reset the .htaccess and wp-config file and edit the mysql like stated above and your site will come back when accessed without the https.

      Good luck!

      Best,

    I am not able to access the admin area after I uploaded define(‘FORCE_SSL_ADMIN’, true); to wp-config.php. My site was already using wordpress https plugin with force ssl administration checked in. I removed that plugin using ftp but I am still not able to login. It says incorrect username or password. However neither the password nor the username has been changed. I think this was the problem after I tried adding define(‘FORCE_SSL_ADMIN’, true); to wp-config.php. I can see the login page on https version of the site but not able to login. Please guide further.

        I’m hopeful you ran a back up before doing any changes to your site.. in either case revert back your site to an earlier state via your database, and whatever back up of your config.php file you have.

        I had a similar problem after enabling FORCE_SSL_ADMIN in wp-config.php.

        The login page etc. was coming up ok over HTTPS but it wouldn’t let me login successfully.

        In this case, it was a plugin interfering – “Chap Secure Password Login”. After deactivating it, logins worked ok (and in fact, it’s not needed when WordPress is configured to force SSL on the admin page).

        So I would suggest checking any login related plugins and try deactivating them.

        Another issue is if you are using something like HAProxy in front of your webserver for load balancing, and get something like a “too many redirects” error message after trying to move WordPress to HTTPS.

        In this case, you most likely need to modify wp-config.php to tell WordPress that the connection is actually HTTPS, otherwise it will keep trying to redirect even when the client connection is over HTTPS. There are some details here,

    Hi, I followed your tutorial. Thanks, Everything works! But I am getting an error when I load the home page saying “Your connection to this site is private, but someone on the network might be able to change the look of the page”. I checked it out and it seems there is a problem in one of my font resources which uses Google Fonts with http instead https, can you show me how can I fix this?

    Thanks

    • Sebastian

      Try removing the “http://” from the Google Font call. So it’s not being forced across HTTPS. The reference call to the Google Font link should start with the “www.” instead of “http://”

    We installed the plugin WordPress HTTPS (SSL). We chose to only use SSL on specific pages option and everything is working great. However we have two important questions that came about after reading the GOOGLE article about migrating to https. Not sure if I can share link on here, so this is the title “Secure your site with HTTPS” on support google.
    Questions.
    1. Does the plugin WordPress HTTPS (SSL) automatically create 301 redirects to help search engines know we moved to https on those specific pages?
    2. If the plugin does not create the 301 redirects, do WE need to go ahead and create the 301 redirects manually for those specific pages that we added SSL on? Thank you in advance

    返信

    • WPBeginner Support

      See if the plugin is redirecting by checking it with an online redirect checker tool. If it isn’t, then you can setup your own redirects.

      The easiest solution is to delete the plug-in.

      Access the files on your server (If you are using cPanel, you can use ‘File Manager’
      Browse to where the plug-ins are kept

    Fantastic guide, simple and usefull.
    The only thing to worry about is that the redirects causes the page to slow a bit down.

    Is implementing the code listed above into the .access file the first choice or is it better with just a plugin?

    I´ve chosen both options, that means both a wordpress https plugin AND .access code.
    Would you say that is benicial or not?

    Thank you for your guide. I add this code in my htaccess file
    RewriteEngine On
    RewriteCond %{SERVER_PORT} 80
    RewriteRule ^(.*)$ https://www.yoursite.com/$1 [R,L]

    but now it do not do 301 redirect it is doing 302 redirect.
    Please tell me is it ok to do 302 redirect or not.

    Regards

    返信

    • WPBeginner Support

      A 301 redirect means that the page has permanently moved to a new location. A 302 redirect means that the move is only temporary. Search engines need to figure out whether to keep the old page, or replace it with the one found at the new location.

    Thanks for the article, but I should definitely have read it before adding the SSL and https to WP. Total newbie but somehow managing a wordpress site..

    Changed WP site address on the settings page from http to https after an update recommendation on my admin panel. But now I can’t access the website or admin page! All I get is a blank page with the message ERR_TIMED_OUT and site can’t be reached.

    I realised I hadn’t activated the free SSL certificate that comes with our web hoster. Now I have done that and I’ve tried adding a WP SSL redirect (http to https) code to the .htaccess file as well. And tried adding define force_SSL_admin to wp-config.php, but nothing has changed and I don’t know how to undo or fix the issue. Any suggestions or experience in this issue would be very helpful!

    Thank you for your article! I was wondering though, my website recently has suffered some problems with “too many redirects” error. I wonder if adding the .htaccess code you mentioned in the article for ssl redirect will make the problem worse? Some visitors to my website said they often see “this page isn’t redirecting properly” when they come to our website. Could it be that our customers are having trouble visiting our website because I don’t have that code in my .htaccess file?
