19 Tips for configuring .HTACCESS file to prevent your WordPress site from hacking

Do you know the WordPress .htaccess file? The .htaccess file is a directory level configuration file that allows decentralized management of the web server configuration. A .htaccess file is always added to the root directory and with it many WordPress configuration parameters can be modified.

With the .htaccess file you can edit the server’s global configuration, the content type and the character set. With all these properties the .htaccess file becomes the key that guarantees and improves the functionality of web pages and blogs that have a WordPress installation.

SEO and .htaccess

The .htaccess file is vital to do a good job of positioning in search engines. As an SEO consultant, when it comes to positioning a page or blog in search engines like Google, I use it for:

  • Create redirects: For example for a domain change job, where it would be necessary to maintain the visits of the previous domain.
    Improved loading speed by enabling compression with .htaccess: It is a section that very few web pages use and that gives very good results.
  • Link rewriting (URL)
  • Solutions to duplicate content: For example, capturing access to certain contents so that they are no longer duplicated.
  • Moderate comments

When you install WordPress, a .htaccess file is always created which WordPress uses by default. This file can be improved using the following tips. While you should be careful when implementing them, and always keep a backup before changing anything, in case you have to go back.

Tips for configuring the .htaccess file

Here are the “19 htaccess hacks to prevent your WordPress site from hacking” to know how to configure and optimize .htaccess to avoid “Hacking” that will greatly hinder and prevent piracy on your website or blog in WordPress. Some of these tips are for:

  • Block specific IP addresses
  • Reroute visits to the maintenance page when designing a particular website or blog
  • Restrict IP addresses so that no one can access your WordPress admin panel
  • Other different tricks or tips for configuring and optimizing the .htaccess file in WordPress.

This article will help you configure .htaccess to avoid “Hacking”, but if you really want to deepen and configure your .htaccess file correctly you should read the .htaccess reference guide.

#1 Block IPs from unwanted users or bots

Apache can be used to block unwanted users or bots to our website or blog. This code allows anyone to visit the website or blog, except anyone who has the following IP addresses (change the IPs with the IPs you want to block):

<Limit GET POST PUT>
order allow,deny
allow from all
deny from 135.456.789
deny from 95.131.738
deny from 253.916.729
deny from 135.468.910
</LIMIT>

#2 Redirect the day and name of the permanent links to /% postname%/

The first thing you need to do is access your WordPress admin panel, go to Settings → Permalinks and select “customize”. Fill in the field with /% postname%/:

Now we have to redirect all backlinks using the old permanent link structure (permalinks) to the new permanent link structure. To do this, you will have to edit the .htaccess file and insert the following lines of code:

RedirectMatch 301 /([0-9]+)/([0-9]+)/([0-9]+)/(.*)$ http://http://www.yoursite.com//$4

If you want to configure more optimal permanent links, I advise you to change /% postname%/ to /% category%/% postname%/.

#3 Reroute visits to a maintenance page

RewriteEngine on
RewriteCond %{REQUEST_URI} !/maintenance.html$
RewriteCond %{REMOTE_ADDR} !^135.135.135.135
RewriteRule $ /maintenance.html [R=302,L]

#4 Redirect to www or without www with .htaccess

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^yourblogname.com [NC] RewriteRule ^(.*)$ http://www.yourblogname.com/$1 [L,R=301]

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} &lt;font color=”#ffff00″&gt;Sync by honeybunny &lt;font color=”#ffff00″&gt;http://tu_dominio.com/

#5 Configure canonical URLs with .htaccess

# Set the canonical url

#6 Redirect your feed to FeedBurner

#7 Redirect your comment feed to FeedBurner

# temp redirect wordpress comment feeds to feedburner

#9 Forcing the cache from .htaccess

<a class=”_hootified” a=”” href=”#” #trailing”=”” onclick=”javascript:var e = document.createEvent(“CustomEvent”); e.initCustomEvent(“hootletEvent”, true, true, {type: “hash”, value: “#trailing”}); document.body.dispatchEvent(e); return false;”>#trailing</a> slash enforcement
