I've got a very strange problem.
When I create a category that has polish characters in the admin panel, there is an error, when I try to add an article to this category.
After clicking the save&close button article is published , but simultaneously there is a message:
Save failed with the following error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' SQL=SELECT * FROM `gbso3_finder_taxonomy` WHERE `parent_id` = '257' AND `title` = 'Nieruchomości'
and article doesn't close. I need to close it manually.
Category name is "Nieruchomości" - you can see it in the communicate above.
Do you have any idea how can I resolve this problem?
I'd like to add that I've installed polish language for the site and admin panel.
