This is just happening on my computer only, not sure why... I removed the language choice from my templates..
 
How do I change them back to English? My static messages admin page says they're in English already, but still show up in French.
 

I wonder whether you need to re-instate the options, select your browser to view the English version and then remove the options?
 
Just an idea

Thanks Christopher,
 
Yea, I did that but it still didn't work - so I replaced the French message files with the English ones... Not the best solution but it'll do for now, I don't anticipate needing French language support anytime soon.
