@Marostegui do you know who can do it?

@Aklapper sorry for ping. Do you know who can clean the database? There are still pages defined in that now-undefined namespace in the database.

Namespaces 104 and 105 were removed per T298315. Shouldn't they be removed from WikidataPageBanner too then?

37 rows in 105 => 'Discussioni_tematica'

SELECT page_title
FROM page
WHERE page_namespace = 105;

and 226 rows in 104 => 'Tematica'

SELECT page_title
FROM page
WHERE page_namespace = 104;

this should be cleaned up. I do not know whom to ping, who may do it.

There are still a couple of pages defined in that now-undefined namespace in the database. This shoul be fix before closing this issue.

Thank you for your fix @Physikerwelt !

I will reopen this issue, all formulas is broken, see https://m.wikidata.org/wiki/User:Physikerwelt#Test and T338381

I think the problem is in https://phabricator.wikimedia.org/diffusion/EFLR/browse/master/business/RevisionReviewForm.php$300

I wanted to report the same error. When I tried to approve https://ru.wikipedia.org/w/index.php?oldid=126470977 I got {"error-html":"<p><b>Невозможно проверить версию.</b>\n</p><p>Не существует такой целевой версии.</p>"}
