What is a 404 error and how do I fix it?

A 404 Error, also known as a ‘Not Found’ error, indicates that the resource a website requested couldn’t be found.

1. 404 error across the whole website

This is commonly caused by the site’s Document Root being set to a folder that doesn’t exist. Fix it by:

• Log in to MyMultidata and select the package under Manage Hosting
• Head to the Domains section and check the Document Root is pointing to the folder containing your site files
• Update and allow 15 minutes for the change to take effect

2. 404 error on all subpages in WordPress (but homepage works)

This is caused by the permalink structure not being set up correctly:

1. Log in to the WP Admin area
2. Go to Settings > Permalinks
3. Make sure the correct URL structure is set, then hit Save Changes

3. Site images returning a 404 error

Check the File Manager to confirm images exist in the correct location, and verify the file paths in your site’s configuration are correct.
