WordPress’ Permalink settings have an important impact on the generation of 404 errors. If you have recently changed your Permalink settings, this may cause some links to receive 404 errors. Please go to Settings -> Permalinks in WordPress backend and make sure you select a correct Permalink structure. It is usually recommended to select "Post Name" or "Custom Structure", then save the changes and then check if the link is available on the website.

  1. Check the .htaccess file

The .htaccess file is a configuration file that controls URL redirection and links on the WordPress website. If there is a problem with this file, it may cause a 404 error. . You can access the .htaccess file in the root directory of the website through FTP or a file manager to check whether there are syntax errors or improper configurations. The following is a simple .htaccess file example:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
Copy after login

Please make sure your .htaccess file is consistent with the above example, save the changes and refresh the page to see if the 404 error is fixed.

Sometimes, 404 errors may be caused by theme files or plugins. If you have recently installed or updated a theme or plugin, this may cause a 404 error.
