I am running the Sitemaps plugin, which was last updated by Vanilla team in 2019. My forum version is newest one (2021.009). I have a problem that it adds a noindex tag to some URLs, like the following example: https://domain.eu/categories/archives/some-category-name/2021-05
The fix is mentioned here: https://open.vanillaforums.com/discussion/38465/robots-noindex-on-categories-archives-despite-being-used-for-sitemaps-plugin . However, I have tried to add it to: vanilla/applications/vanilla/controllers/class.categoriescontroller.php as mentioned here: https://github.com/vanilla/vanilla/issues/10970 , but it didn't fix the sitemap. Any ideas on how to workaround this? I'd prefer not to do any custom coding, as it will get overwritten by potential updates.
