Hello there,

Try to flush your permalink by doing these steps: From dashboard, go to Settings > Permalinks > just his the Save Changes button. Then reload your homepage. If it doesn’t resolve the problem, the .htaccess file might not be able to update on your root folder of WordPress install. So you would update it manually. Please see the WordPress codex: https://codex.wordpress.org/Using_Permalinks#Automatically_updating_.htaccess.
