Thankyou for that, my husband sorted it thank goodness. I have to use it a bit differently for some reason.Oh darn. That sounds frustrating for you.
Do you know which browser you're using (Chrome, Safari, etc.)? Since there's nothing obvious that's changed at our end, the first thing I'd suggest would be to try a different browser or device and see if you can see/use the smileys and text formatting. If you can, it's probably browser-related.
Let me know how you get on and we'll go from there and see what else to suggest.
