You mean add tags after the fact? Only a mod or the OP can edit a topic and add them.
Tags are not available for posts but I really, really, wish they were.
I've encountered that sitemap.xml file contains the links to topics that has been removed, but not the fresh(currently live) topics. Why it is so?
I doubt it's an expected or designed behavior
The code looks good to me what version of nodebb are you running? Is your site public?
Guys, any suggestions?
@Tom-Riddleff That is quite weird. Would it be possible for you to provide us a copy of your database so we can investigate the problem?
