If you disable wpForo cache you'll not fix the issue. You'll just have an heavy loading forum, nothing else. As I've already mentioned the issue doesn't have direct relation to wpForo so there is no mean to disable wpForo cache.
I recommend install some cache plugin, for example WP Super Cache and the Cache Control attribute in your page header will be changed to this and it'll work fine:
Accept-Ranges |
bytes
|
Cache-Control |
max-age=2592000
|
Connection |
keep-alive
|
Content-Encoding |
gzip
|
Content-Length |
19815
|
Content-Type |
text/css

Don't forget exclude the forum page in this cache plugin settings:

I was suggesting WP Super Cache.You can install it and check.
However I put a wrong link for the option to exclude forum page. Here is the correct link: http://support.jawtemplates.com/goodstore/web/?p=491
Just put as a new line your forum base URL, for example:
- /community/
- /forum/
- /foro/
whatever is your....
Also I'd suggest WP Performance Score Booster plugin.

I'm using super cache for years without any problem.
