I\'ve re-installed WAMP multiple times, searched literally hundreds of pages, and its not fixed this issue:
To change the language that MySQL uses when reporting you need to change the my.ini file as follows.
Find this line:
# Change your locale here !
lc-messages=fr_FR
And change it to your prefered language, for example:
lc-messages=en_GB
To change it to English US, you can do like this:
lc-messages=en_US
Save the file and then restart MySQL.
left click wampmanager icon -> MySQL -> Service -> Restart Service
Remember the guys that produce WampServer are French so I guess thats why this has been added to the my.ini file, and they just forgot to remove it on this release.
Use the wampmanager menus like so :-
left click wampmanager icon -> MySQL -> my.ini
This will load the my.ini file into your editor.
Here you can find a list of valid locales
