I just upgraded from 2.2.1 to 2.2.2 using Fantastico, which caused foreign characters to be all messed up as per this thread:
It also made all my text widgets disappear. So I added all the widgets back.
Then I followed the directions in the thread above to add back these two lines to wp-config.php:
That was the fix when I upgraded TO 2.2.1, and it did work again when the same character problem occurred with the 2.2.2 upgrade.
However, fixing it this time made my text widgets disappear again, so I re-added those two lines, and got my widgets back.
Please have a look--you can see the character issue easily as one item in the menubar is "Preguntas Frequentes..." in Spanish. I am using Cleaker 2.1 as a theme.
Any suggestions for making my foreign characters work
