Sometimes, forum is broken as attached picture and when this happens I need to close all the web browers and launch->login again to solve this problem and when this happens I can not manage the posting.
for example, in the attached picture the posting was a spam so I tried to delete, but it was not deleted, but when I clicked on delete button the sqaure box kept swinging and nothing happened.
This problem frequents so can you tell me how to solve this?
This issue has no any relation to wpForo. This is your internet speed and browser cache issue. The screenshot says shows that icons have not been loaded. The only reason is not stable internet connection or browser cache issues. So I recommend change your internet provider or the device/browser.
