Hello John,
I hope you are well today.
I couldn’t reproduce the issue on my end. When a user registers, the activation message seems to be shown correctly.
It’s possible that the problem is caused by a caching issue. Please clear your browser’s cache and, if you’re using a caching plugin, please try and disable it.
If the issue persists then would it be possible for you to share your WordPress dashboard access so we can take a look for you? You can send your details to [email protected]
Kind regards,
Moshtafizur
