Sometimes after a restore, the homepage will look okay but clicking on any other link will lead to 404 errors. This indicates that the .htaccess file needs to be regenerated.
To do this, you can go to the Settings > Permalinks page in your WordPress dashboard and save the settings there.
Note: You do not need to actually make any changes on the Settings > Permalink page!
If you still are seeing 404 errors after doing this, just contact us.
