I guess I found a workaround… not the most elegant solution but it seems to work…. Instead of calling a category directly, I created a Page, which contains all the posts of a category…. So when I open this page I see all my posts as I did before the update without any error message…
How to do this?
1. Install and enable the Allow PHP in Posts and Pages Plugin
2. Create a new Page and insert the following code:
[php]
query_posts('cat=x');
[/php]
Change the x to the ID of the category you want to show.
3. Change the links in your menu that directed to the category for links to your newly created Page
4. I had to change some CSS in order to fix some little design problems
Repeat steps 2-4 for all your categories in all languages…
Done!
