Map on openstreetmap.org not working correctly

1. Always starting at lat 0 lon 0 at zoomlevel 1 2. No new options, no data option 3. Click on search results ---> Backk to 1. Total mess

Mapnik rendering of this one forest is light grey instead of green

Look at: osm.org/?lat=49.6466&lon=6.814&zoom=14&layers=M compared to the rendering at a bigger scale: osm.org/?lat=49.6381&lon=6.80...
