The issue in your Firebase configs.
Even if you DO NOT use Firebase for push notifications, you should never remove the Firebase Web Push Certificate from the Foodomaa's Admin Settings Panel.
Go-to Admin > Settings > Push Notification > Firebase Web Push Certificate
This "Firebase Web Push Certificate" filed should not be empty.
Please set it to:
BH5L8XrGsNpki5uF1008FbZzgKKZN-NmhOwdWL5Lxh5r3nsgZ6N_Dged1IYXXCCJwpnrXzs52G_v3vM_naO0hxY
And save the settings.
Then you can reload the page. (or better do force cache clear and reload the page)
