the current included xcgal plugin in the sitemap download has taken the info from the wrong fields, resulting the hierarchical view of the xcgal categories are incorrect.
i made a fix, which can be found at:
xcgal plugin for sitemap.
It is regret that "sitemap" is not a project in sourceforge.jp/xoopshackers.
Thus, I can't touch it directly.
I'll claim it to Ryuji
just wait or send it to Ryuji himself.
hi karedokx.
I've just replaced it.
