I updated from Piwik 0.2.26 to 0.2.28 yesterday. Since that time, clicking on the Api-Link in my Dashboard shows me an empty page. Even the source of the page http://-deleted-by-me-/piwik/index.php?module=API&action=listAllAPI&idSite=1&period=day&date=yesterday is totally empty.
Amy ideas what could be the problem?
Second problem since 0.2.28: The table at actions -> pages shows no further entries when I click on one of the labels/categories that have a “+” in front of them. For example I have the label/category restaurants that showed several entries every day until the update to 0.2.28. Now it only says “No data in this category.”
