Hello, I'm using the Ajax Event Calendar on my WordPress Blog, but since I deleted a few categories and created new ones, the category numbers go like this: Category 1, Category 2, Category 5, Category 9, Category 11, and so on. The problem is that all the events submitted in the categories after Category 2 don't show up on my Calendar, even if they are perfectly visible in the working mode. How can I change the category numbers so that all my events are shown again? Thanks in advance.
