How can I create custom error pages, e.g., 404?

To display custom error pages, you need to place a file named ".htaccess" in the relevant web space directory and insert the following content:

• ErrorDocument 403 /403.html
• ErrorDocument 404 /404.html
• ErrorDocument 500 /500.html

Files such as 403.html represent the error page to be used, which is created by the user. It is important to note that the error pages must not be placed in a subfolder named "error," as this is reserved by the system. PHP error pages are not supported.
