How to change monodevelop errors & warnings language

Mine are in spanish (sort of…) I want them in english, Im spanish but seriously I cant understand them, its like it was translated with google translator or something.

I know how to change the interface language but I dont see any option to change error & waning messages language.

See configuration - Change compiler errors language in Visual Studio 2013 - Stack Overflow

In Tools menu select Options. In options window pick Environment category, there you can find Language options. Click on it and set User Interface Language to English. Don’t forget to restart Mono.
Good luck!

I’d advise to stick with english for the editor, alot of the coding is actually derived from english words. It is easier to learn and understand this way too.
