I have also noticed that this only happens when the user is editing content based on their role. If the same user logs in as admin the issue doesnt occur.
Hi,
Yep, this has been resolved now - thankfully!!
It appears that as part of the English language pack installed there is an ‘English (United States)’ option. If the user chooses this option they get American speak, if they choose the language ‘English (United Kingdom)’ it works as normal.
This is changed via a drop down list on the far right hand side of the screen.
Simple really!
