1.1) BrainKing pages are shown in a foreign language which I don't understand. How can I fix it?

This situation can occur if you, for some reason, click on some language flag at the right column of any BrainKing page, then confirm this change and forget to switch it back. Please follow these instructions:

1. Log in with your user name and password (it should not be difficult to guess which field is for "user name" and which one for "password" because the login form structure is always the same).
2. If you don't see the language flag column at the right edge of any BrainKing page, you are probably using other style than the default one. Please find the "Castle | Simple | No fonts" line at the top of the page and click the Castle link to switch to this style (it should not be a problem because style names are never translated and always shown in English).
3. Find your language flag at the right column and click it.
4. Confirm the change when the confirmation dialog appears.
5. Your language version should be back.
