When you update to the current version of the phpBB3 forum software (3.o6), the section for Active Topics is turned off by default. I did a little looking, and found out it’s just something you need to turn back on.
There was a bug in the previous versions whereby the option for active topics was on regardless of the admin panel option. This has now been fixed and so the default ‘no’ option is actually working correctly.
Turn on Active Topics in phpBB3 Forum
- Go to the Admin panel
- Choose “Manage Forums” under the Quick Access section
- Click the green cog next to the forum you want to include.
- Change “Display active topics” to Yes.
- You can turn it on for all forums by using this query on your database. NB you may need to change the table prefix to your own.
A member of the phpBB forum mentioned that you can turn it on for all forums by using this query on your database. (I’m no DB expert, though, so run this at your own risk…)
UPDATE phpbb_forums SET forum_flags = forum_flags | 16 WHERE forum_type < 2;
Found all this info on the phpBB forum
