Ensure that the language that you just added is selected on the left side. Next, you have to set it as default language.

A new windows appears, select a language that you want to add and click OK (the left button).On Languages, click Add button (the last button on the page).On right side – Web Content section (the second section from above), click on Languages and spell-checker settings (the last button in the section). On Settings, select Under the Hood (the third tab on left side).Open Google Chrome and click on the wrench icon -> Settings (the fourth option from bottom of the menu).Note: In this example, I use Google Chrome 18. The configuration steps are the same, only difference is the language. On the right are screenshots for change language from English language to Thai language.

On the left are screenshots for change language from locality language (in this example, it is Thai language) to English (United States). To help you better understanding, I have provide two screenshots for each step.

Note: If you want to see how to prevent this problem from the beginning, see at the end of this post or click here. If you are not familiar with the default language, it is very difficult to navigate through settings in order to change the default language so I write this post to guide you how to change default language on Google Chrome Browser.
