Sub Forums: xxx, xxx, and 7 more.
How can I show all of them?
ACP > Configurations > Forum Home Options > and enter some bigger value e.g. 13 in "Subforums to show on Index listing" option field.
Edit : not seen
Yaldaram's response
admin panel --> configuration --> settings --> Forum Home Options
--> Subforums to show on Index listing <-- use a higher number eg. 33
AND you may also use
this plug-in to arrange subforums listing in columns
