I have an ad that I want to place on one certain category and on the blog index/home site. So I choose to show on certain types: home, single and category. Then I click on the extended restrictions tab and enable to display ONLY in single posts or categories archives. But if I do so, it will not be shown on home. So I altered it to the option thereunder (TO NOT display in single posts or category archives) and selected all categories but the one I wanted the banner to be shown. Now that seem to work so far. Fine... But, after I've saved that ad, some checkboxes uncheck themselves. I tried to check them again, but if I save, they are unchecked again. What to do? Seems like a bug.
