Blukkie, to check this issue we will defenitely need to log in to your site as this user.
Will you be able to PM me access details along with your site URL?

What I am going to do is to debug this using Firebug.
If you know how to use any debug tool you can do this yourself and there will be no need to give access details to me.

Thank you Allia,

I sended you our information in PM. Thanks alot for offering the help!

Found anything? Otherwise I think the user will delete the account and try a clean one.

Didnt hear anyone else have this notification bug, so maybe its one time only?

Meanwile I checked some things to try resolve this notification problem;

Our site is in Dutch language packet. When I enable English language packet and log in under her account. I can see the notifications without problem. When I switch back to Dutch, the notification is loading forever again.

Maybe the Oxwall team has an idea now what the problem is? Still, only she has this problem.

Blukkie, I have contacted developer of "Smileys" plugin, which is causing this issue on your site.
He will fix this and update his plugin asap. You just need to wait.

Thanks alot Aliia!

I will de-activate this plugin and wait for the update.
