Our plugin is very popular and we get a lot of support tickets, for best results please reach out to our support team to assist you in our designated support channel [email protected] or the intercom chat in the onesignal.com website or documentation: https://documentation.onesignal.com/docs/wordpress
Further, I checked out your site and it seems to be working correctly for me. Can you try resetting your browser permission and cookie data and try again: https://documentation.onesignal.com/docs/troubleshooting-web-push#clearing-your-cache-and-resetting-push-permissions
If you can reach out to [email protected], we would be happy to assist you further.
