Dear Nor, 

thank you for your message. 

If you want to create a website in a language that is not included in the list of available languages (for example, Portuguese), to avoid having the automatic text added in English (which is the default language), you must add a new language to the list. You will also need to provide the translations of all the texts, so make sure you have these available when you want to add a new language. Once you have the necessary translations, adding a new language is easy:

• In the Language Content Management, click on the Add a new Language button and type "PT - Português" in the dialog box that is shown. This new entry will appear at the bottom of the list of available languages.
• Click on "PT - Português" to display the column for this language in the translation table.
• Type in the translations for each item and then close the window when you have finished: this automatically saves your work.
• Set "PT - Português" as Content Language in the General Settings window.

Please let me know if I can help you further. Kind regards.
