Since the newest update 1.6.0 (it's pure coincidence that I did an update so fast), it destroyed the layout of the forum for me. On the left side I see the forum as usual, but on the right side about 40% of the screen is nothing. As if it had moved the forum about 40% to the left side. Apparently, the last posts of the users should be visible on the free right side. But on the right side nothing is to be seen. What happened there? How can I fix this bug?
UPDATE: It's done. I found the setting. It was a widget problem.
Thank you for the update. Also please delete all caches and press Ctrl+F5 on forum front-end to reset browser cache. After updating any plugin you may have lots of problem if website cache and the browser cache is not delete properly.
Thank you for pointing that out. I had cleared all caches before and read your hints from the announcement about the new v1.6.0 update and therefore updated the database in the debug tab.
It was the widget. In WordPress I could set it under Appearance and then Widgets. There I went to the "wpForo Sidebar". Unfortunately there was no entry at all, it was empty. I then added "wpForo Online Members" and also the "wpForo Search" widgets and then my problem was solved. Then both sides of the forum showed something on the left as well as on the right.
