   Hi. Really nice article.

   I had a 500 internal server error issue with my site when I tried using the W3 Total Cache plugin.

   To fix this, I renamed the .htaccess file to .htaccessbak. After doing this, I noticed that the 500 error cleared but then I got a 404 error! All the links and pages on my site returned a 404.

   On the All Pages section, I see a link that says “Purge from cache”

   Please what do I do to clear this issue?

   I tried to follow your direction in fixing my problem, it took for about a day, but I didn’t find the good result.

   Then I gave up and contacted my hosting. And it fixed only in 5 minutes. Lol the problem came from the hosting…

   By careful with post variables names. I had a contact form with an input field called “name”, that caused WordPress to show the 404 page. Took me a long time to figure out the problem. I fixed it be changing the field name from “name” to “your-name”.

    Hi, I have tried following the above steps but my issue is this: when I visit my website directly by putting typing the url, then it works fine. But, when i type in my site url in google search box and then click on the link from the search results, I get the 404 error or message saying “your connection is not private”.
    My website is http://www.example.com but google search result shows it as https://example.com/

    So not sure what the issue is. I used to have wordpress.com but now I am dong self-host using HG.

    Any help will be appreciated.
    Thanks

      www is considered a subdomain of a domain. So basically a site with www and without www will be considered two different sites by search engines. Go to Settings > General page to change your site URL from http://www.example.com to just example.com.

      WordPress.com enabled https for all custom domains on WordPress.com. This means Google had already crawled your website with https in the URL. You can install free https using Let’s Encrypt.

    hi, I tried first solution, nothing happened. I wanted to try the second, but I cannot find the .htaccess file. Not in FTP, not even in my WP online editor. I had this issue today for the first time. I use WPML plugin, until now everything went without problem, but today my translated post in English throws this 404 Error. Any idea what shall I do if I cannot locate the .htaccess file?
    Thanks!

    • Michaela

      I noticed one thing. The post in the editor shows me the following link:

      example.com/2016/09/15/where-eat-in-barcelona/?lang=en

      but when I click to see the post, or from any RSS feed click on the published post, the link showing 404 error is as follows:
      example.com/?p=11409&lang=en

    Well thanks! I remember, that WP Super Cache official stated to remove rewrite code from .htaccess. After that, my posts redirected to 404. Thanks to you, now my site is perfectly fine.

    Sir, when I post a new post it gives me error that 404 page not found. Previously everything was fine but when I add a new user and give him a role of administrator from that time I can’t post new post. Any solution Please. Thank you in advance.

    返信

    • WPBeginner Support

      You should never give administrator role to a user you don’t trust. You can always change back their role by going to Users page and then clicking on the Edit link below the user that you want to change. After that you check your site’s permalink structure. See if they installed any new plugin and if they did, then deactivate that plugin.

    Didn’t work on my apache server. Had an additional step to allow mod_rewrite to actually work. Edit your httpd.conf file and add ‘Allowoverride all’. For example:

    DocumentRoot /var/www

    find the section that sets up the directory options, such as:

    Options Indexes FollowSymLinks MultiViews
    Order allow,deny
    allow from all

    add Allowoverride all

    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
    Order allow,deny
    allow from all

    save and restart the web server to re-read the updated configuration.

    All was well after that.

    Thanks for your useful post moving me into the right direction.

    Hello and thanks for all the useful tips. Unfortunately, this tip didn’t work for me. I re-saved my permalinks in WordPress settings (didn’t work) so then I tried your next method and it didn’t work either. I’m thinking the reason for this is because I have different permissions. My original permission is 644. When I change permission to 660 none of my pages work so I believe the 666 permission is wrong as well. I’m using a Go Daddy server if that helps any :/

    I’m at a loss and have no idea what to do from here. However, I can’t afford to have pages that don’t work. Any suggestions would be greatly appreciated.

    Thanks

    I had this problem after moving sites to a new server. Default Permalinks worked, but not the settings I was using.

    I needed the apache server to “Allow Override” for the htaccess file to take effect.

    Hi,

    I need a little help regarding 404 error.

    I am getting 404 error in my Page 2 section.

    I have googled a couple of times. but did not get the solution.

    Could you please tell me what is the reason for it?

    My site links will work ONLY after I’ve VIEWED the permalink settings, without any changes, and Voila! The links work again. What is causing this and how can I program this instead of having to log in?

    I’ve tried the following commands in WP-CLI to no avail:

    wp rewrite flush –hard –path=c:\xampp\htdocs\mywordpress

    wp cache flush –path=c:\xampp\htdocs\mywordpress

    Hi there,

    About an hour ago I was able to remedy a pesky ‘500 Internal Service Error’ by following your sage advice and renaming the .htaccess file to .htaccess_old. I was immediately able to access my wp-admin area–and I thought–get going again.

    Unfortunately, something happened which rendered all of my other pages unfindable; each kicking a 404 error.

    I attempted the steps you provided above, but to no avail. Might you have any further suggestions?

    Thank you.

    Hello agin
    thank you for this useful article/ I found a bug in wordpress in rtl language in displaying permalink
    I read your article and encourage to solve the problem with your contribute.
    ——————————————
    my problem in detail:
    1-I created a mysql database(in utf8 general ci)
    2-I installed last wordpress versin(locally) and install my theme(multiup v 1.2 from themeforst)
    3-Next I did import demo as whele.
    in the theme admin panel exixst category portfolio (in this section we create our category with name and slug) then in all post under portfolio section we can create our posts and determine category of post from portfolio category) finally in homepage we have a section that shows portfolio post in category(with their picture)
    In english slug and name the category of portfolio show well but when i change category in portfolio category( slug) into rtl language the category in homepage canvert into charachter like base 64(I think that my slug convert into ansi ie each character convert into 6 charachter)
    How I can overcome my problem?I think I must avoid change slug or show slug into utf8 or unicode . I am beginer in wpordpress , If I khnew wordpress more I could solve this simple problem .Any one with khnowledge of handling hoock and filter and plugin and wordpress can solve this permalink problem . I sure I will solve this problem with your help.
    ———————————-
    I tried the second way you offer (that phpmyadmin in utf8generalci) but it doee not work for me.
    before thansk a lot for helping me.I followed your posts regularly .
    ……………………………….
    1- first I did the trick in above article (this is so good but didnot solve my problem)

    hello
    thanks to contribute you knowledge to others .my english is not well.excuse me.
    I download a wordpress theme with portfolio link in admin panel that in porftoli section we can define some category with name and slug . in post we can determine category from portfolio.
    in homepage we can display post in portfolio category! all thing is ok but wen i chang name and slug into rtl language the title of a group in home page shows like this %d8%a8%d8%b1%d9%86%d8%af%d8%b3%d8%a7%d8%b2%db%8c
    i did your solution in this topic and that another topic(How To Enable Custom Permalinks) but not woks for my problem!

    返信

    • WPBeginner Support

      This could happen if your WordPress database is not using UTF-8 character encoding. Please make sure that your database is using utf8_general_ci as collation. You can check that using phpMyAdmin from cpanel. Before you make any changes to your database, please create a complete WordPress backup first.
