[Mediawiki-l] UNIQ tags how to get rid of them

[aretai aretai]

Hi,

I am using Mediawiki 1.6.7. When I use some of the extensions for example
calc

http://meta.wikimedia.org/wiki/Calc

There is message like this: UNIQ-calc-QINU. In fact there are some letters
and numbers between UNIQ and QINU, but just have ommitted them.

Only the last

<calc></calc> message is displayed properly (per page).

I found some info on these problems here:
http://meta.wikimedia.org/wiki/MediaWiki_extensions_FAQ#How_do_I_render_wikitext_in_my_extension.3F

However am not sure how to change calc code to have it displayed properly -
anyone could help?

thx

Aretai
