[Mediawiki-l] Categorial misbehaviour

[Plamen Gradinarov]

Categories started suddenly to behave chaotically, appearing sometimes on four places, like here, in the beginning and in the end of the page:
http://www.francopedia.org/Bouddhisme.html

The categorylinks_table is up-to-date (just imported the last dump).
Nothing to do with the templates - everywhere one and the same picture.
Nothing has been changed in the static files. Yesterday all categories were funcional.

Any suggestions where to look for the causes?

Thanks in advance,

Plamen
