Step Two: .htaccess Modifications
1.) Nitro settings.
Access Nitro settings.
2.) htaccess tab.
Click the tab titled htaccess and turn on each switch. For clarity's sake, the Enabled switch means ON and the Disabled switch means OFF. After turning on these switches, click the Save Changes button at the bottom of the tab.
3.) Reset permalinks.
After saving these settings, please reset your permalinks by clicking the Save Changes button on your permalinks page.
Please know that if any of your other plugins have made changes to your .htaccess file, then saving your permalinks may cause an issue on your Divi website. Please make sure you have access to FTP or CPanel when saving changes because if there is an issue you can simply rename the .htaccess file to something else and it will work again. You shouldn't have issues but best to be safe.
