With the release of Market versio n3.5, changing any of the text throughout your theme is easy and fully under your control.
You can do everything from change a little of the wording, to an entire translation into another language.
To edit the language file, simply go to the Theme editor tool in your WordPress administration area. (Click on "Appearance", then "Editor".
Open the file named "mkt_language.php".
This file is broken down into various sections. The Market Theme text, the Shopping Cart text, and the Admin Theme Options areas.
Search for the text you're looking to change, and then change the text between the single quotes.
Make sure you do not remove those quotes, or your website will break.
ALSO… It's very important to know that if you use a single quote within your text, you MUST preceed the single quote it with a backward slash "\\" to escape the character meaning.
For example:
What's the problem with single quotes?
would be entered as
What\\'s the problem with single quotes?
It's very important, so don't forget.
Save the file when you're done.
