Cannot browse the events | WordPress.org

Hi,

I asked here earlier help for a translation issue (Finnish was not sown correctly in terms like months, previous etc.). I got good help and installed the version from the plugin page, it fixed the issue.

But now I have another problem: the calendar pages cannot be browsed, only the first listing page can be seen. I noticed that when I click Next events (seuraavat tapahtumat), nothing happens but also the url turns into this:

https://vinhankirjakauppa.fi/tapahtumat/(/?:list)/

What might this mean?

Thanks!
