Today I updated my wordpress from 3.9 to 4.0. Now all the forum’s topics vanished. The forum shows “sorry brother no topics…..”. In my WP Dashboard, the topics are there but when i open its ‘view’ link, the topics are not there except the title of the topic.

Previously, i.e. before wordpress update, everything was fine and I haven’t installed any new plugins
I am using bbpress version 2.5.4

Someone do suggest. the forum is important part of my site.

This is an issue with some themes after wp4.0

Try

bbpress wp4 fix

or

bbpress wp4 fix2

These usually fix it

wow! Great and thanks for quick support. Your plugin really works. Now please tell me, will I have to keep the plugin active all the time or I can remove/deactivate it.

for the moment leave it active, the next version of wordpress may fix the issue, but otherwise just leave it there
