I debugged a bit, and for example http://tools.wmflabs.org/osm4wiki/cgi-bin/wiki/wiki-osm.pl?project=Commons&article=Category%3ATahara%2C_Aichi triggers this: The links in the left table do not point anywhere; a working example would be http://tools.wmflabs.org/osm4wiki/cgi-bin/wiki/wiki-osm.pl?project=en&article=WAMC where the links point to Wikipedia.

I would try to fix this, but the code is uncommented, and I have no idea where the links in the failure should point to instead.

The home page for this tool is apparently https://de.wikipedia.org/wiki/Benutzer:Plenz/OSM_for_Wiki.

Now error.log seems to be quiet. I will inform Plenz tomorrow at https://de.wikipedia.org/wiki/Benutzer:Plenz/OSM_for_Wiki.

scfc claimed this task.

"Tomorrow", "two months after" – what's the difference? :-)

I left a note at https://de.wikipedia.org/wiki/Benutzer_Diskussion:Plenz/OSM_for_Wiki#Warnungen_in_error.log_auf_Tool_Labs; <code>error.log</code> grew 6.7 MByte since December 10th, so this is close enough to "empty" for me.
