 * Hello there!
    I`m having a problem with my wordpress website. I have installed
   Let`s Encrypt SSL for few websites – 2 of them are working perfectly (like HTTPS
   is visible instantly) without any plugin (I have no idea why), but 2 left are
   not working properly. First of all – when I wanted to manually enter “https” 
   every page was showing 404 error. I reinstalled the Let`s Encrypt SSL through
   my hosting (its one-click setup), but problem was still there. After few tries
   with changing settings in wp-config, htaccess, etc., I installed Really Simple
   SSL and activate it. And after that my whole website goes into 404 mode, I cannot
   login, visit any page – it`s totally down.
 * I need to remove all SSL info from wp-config, DB, htacces, and then website will
   still show 404, but after manually entering to /wp-admin with “http” not “https”(
   here`s second problem – after deleting everything about “HTTPS”, my website still
   tries to go into HTTPS mode) I can log in.
 * So, basically.
    Let`s Encrypt -> HTTPS is not working / HTTP is working Let`s
   Encrypt -> Really Simple SSL -> HTTPS is not working / HTTP is not working
 * Thank you very much for your support, and I hope that you can understand me without
   problems.

 * Hi [@vister81](https://wordpress.org/support/users/vister81/),
 * does the homepage work or is that down too? 404 errors can be caused by a number
   of things, most commonly by an issue with the permalinks. Could you follow the
   instructions from this article to see if that resolves the issue: [https://really-simple-ssl.com/knowledge-base/404-pages-wordpress-site-migrating-ssl/](https://really-simple-ssl.com/knowledge-base/404-pages-wordpress-site-migrating-ssl/)?
   If the admin area still redirects to https:// after removing all the redirects,
   you can try to open the site in an incognito window or clear your browsers cache.

 * Thank you [@markwolters](https://wordpress.org/support/users/markwolters/) for
   your answer.
 * Unfortunately I tried everything that you said.
    I`ve got one-page website, but
   even wp-admin or media links are dead.
 * I removed all redirects (even in DB) and I still need to manually delete “s” 
   from HTTPS to log in.

 * Hi [@vister81](https://wordpress.org/support/users/vister81/),
 * does the site still redirect to https:// when visiting over [http://](https://wordpress.org/support/topic/404-after-enabling-plugin/?output_format=md)?
   If all redirects have been removed, the site should load over http:// without
   redirecting. If it still redirects, it could be there’s still a redirect active.
   If you can provide us with your .htaccess file we can have a look. Could you 
   also provide us with your domain name?
 * Mark
