Hi,
I had to do a bug-fix in my acces styles:
I forgot the min-max-zoomlevels for my else-Filter, so right now, from zoom 0 to 10 *every* way with an access-value gets rendered as a black line:
http://toolserver.org/~osm/access/?zoom=3&lat=38&lon=24&layers=B...
I updated the xml-files, so please reload them from ti/styles/qa/ and ti/styles/qai/, so it will deliver empty tiles for zoom 0 to 10.
Sorry for any inconvinience (I guess, serverload is quite high for a zoom 1-tile with all access-lines rendered..)
Regards, Thomas
