good afternoon
I have a problem with displaying topics on my forum. At the moment in the main forum there are 149 topics. If you go to the page with the forum, then there are no more than 15 last topics displayed. The problem is that there is no button to switch pages on the forum, you can watch not more than 15 topics.

1) link to the main forum
2) link to the over 149 topic forum

Can you help me?

This can be your theme issue used on your site so to confirm it just temporary use the any default WordPress theme like Twenty Seventeen theme on your site. If everything works fine then it’s theme issue.
