You can change the default 404 error page of your domain(s) only if you utilize a paid account. You need to follow the steps:
- Login to your Hosting Control Panel.
- Go to Hosting Tools > .htaccess generator.
- From there select Error Handling and then choose Set Custom Error Documents.
- This will generate an .htaccess file with the necessary code for your custom error pages.
Please note that the .htaccess Generator and the custom error pages are only available to users with our paid hosting plan.
