André, i don't mind that you put it as low priority, as long as it is fixed in the next 7 months.
Really, this should be a 10-minute fix for someone used to the javascript interface with wikitext.

Whether it takes 10 seconds or 10 days does not influence priority at all, that's rather severity. Patches highly welcome as that will certainly speed up progress.

«should be fixed in the next 7 months» *is* priority. :)
(or it could be considered milestone, but we don't have one for that)

If someone goes for it tomorrow after seeing the "it's 10 minutes" comment, the better.

Platonides, could you explain the error better? I couldn't find the 'Mwe-upwiz-campaigns-wlm-it-id' message anywhere..

Also where are you seeing this? on Special:UploadCampaigns?

Platonides, could you answer comment 4, please?

MediaWiki:Mwe-upwiz-campaigns-wlm-it-id was used in a campaign as the label for the monument identifier. In the linked version, it contained a link to the monument lists (it could also be a help page...). However, the wikitext was shown as plain, ie. the bare "[[" were shown to the user.
This bug requests that those links work.

Any reason we can't just get rid of the entire 'page name' business and just have wikitext everywhere?

That's perfectly fine for me. Feel free to duplicate this to a “use wikitext everywhere” bug.

That breaks backwards compatibility, with the 'page' fields going away, and the label field itself being just parsed wikitext. Use {{int}} or similar for i18n

I'm Tomasz W. Kozlowski and I approve this patch.
