Hi everybody,
I am struggling to figure out the problem with 4XX status code. I did not have it before, but now I have 41 pages with this problem, it looks like this:: https://www.krakowtourguide.pl/tag/krakow-john-paul-ii-trail-tour/
I think it has started when I added new tags. Unfortunately, I do not know how to fix it, I spent a few hours trying to make it work, but the problem is still there. Could you tell me how can I fix it?
