Regarding wpforo, when I press the button in the menu bar, it only loads a little and stays on the same page.

It is the same as not being able to press the button in effect.

I have had this problem since the day I installed wpforo,
After I changed the theme, these problems stopped, so I thought the problem was solved, but it returned to normal after about a week.

For some reason, when I change the settings about wpforo appropriately, the problem is solved, and after a few days it returns to normal again, so I'm not sure why.
Worst case scenario, I can just tweak the settings appropriately and regularly, so that's what I'm doing now,

It seems that it does not do so from a mobile device, and even if I make an appropriate change to the setting, such a thing that a real button cannot be pushed by all buttons concerning wpforo plug-ins regardless of it happens.

Before wpforo I had bbpress. (Now deleted).

How can I get it to work correctly?
By the way, this is written using a translation tool, so there may be some mistakes.
