Hi all!
I wanted to share a solution to small problem I had with VPSSIM server configuration and icon files in Forums module. This is an nginx installation so you have to mendle with rewrite rules. The rewrite rules posted in the support do 95% of work, but I couldn't make the forum icons to work.
It turns out that you have to edit /conf/nginx/conf/staticfiles.conf file as well. There is a location part regarding graphic files which will override those rules above, therefore you should add to the top of it something like this:
rewrite ^/forum/layout/(.*).(png|jpg|gif) /modules/boonex/forum/layout/$1.$2 ;
Reloading nginx with reload signal is necessary afterwards.
There can be similar problems with attachments, but if I will have those, I will post a workaround here.
