I stumbled on a "Not Found" message when trying to access the forums members list by character (Login subsonicradio.com > Forums > Members > "Find a member: All A B C ...").
Hope that qualifies as bugNot Found
The requested URL /forum/memberlist.php&first_char=y was not found on this server.
The URL looks a bit wacky: http://www.subsonicradio.com/forum/memberlist.php&first_char=x#memberlist; notice the "&" - when replaced by "?" it works as intended.
Might be something with phpBB and custom themes ( https://www.phpbb.com/community/viewtop ... &t=2149769 ).
