404 means the file is not found. If you have already uploaded the file then the name may be misspelled or it is in a different folder.

Other Possible Causes

You may get a 404 error for images because you have Hot Link Protection turned on and the domain is not on the list of authorized domains.

If you go to your temporary url (http://ip/~username/) and get this error, there maybe a problem with the rule set stored in an .htaccess file. You can try renaming that file to .htaccess-backup and refreshing the site to see if that resolves the issue.

It is also possible that you have inadvertently deleted your document root or the your account may need to be recreated. Either way, please contact your web host immediately.

For addon domains, the file must be in public_html/addondomain.com/example/Example/ and the names are case-sensitive.

When working with WordPress, 404 Page Not Found errors can often occur when a new theme has been activated or when the rewrite rules in the .htaccess file have been altered.

When you encounter a 404 error in WordPress, you have two options for correcting it.

Option 1: Correct the Permalinks

1. Log in to WordPress.
2. From the left-hand navigation menu in WordPress, clickSettings>永久链接(Note the current setting. If you are using a custom structure, copy or save the custom structure somewhere.)
3. SelectDefault.
4. ClickSave Settings.
5. 将设置更改回先前的配置（在选择默认值之前）。如果您有一个自定义结构。
6. ClickSave Settings.

This will reset the permalinks and fix the issue in many cases. If this doesn't work, you may need to edit your .htaccess file directly.

Option 2: Modify the .htaccess File

添加following snippet of codeto the top of your .htaccess file:

If your blog is showing the wrong domain name in links, redirecting to another site, or is missing images and style, these are all usually related to the same problem: you have the wrong domain name configured in your WordPress blog.

The .htaccess file contains directives (instructions) that tell the server how to behave in certain scenarios and directly affect how your website functions.

Redirects and rewriting URLs are two very common directives found in a .htaccess file, and many scripts such as WordPress, Drupal, Joomla and Magento add directives to the .htaccess so those scripts can function.
