Forums Bug Reports Dont join in +#chan shown in whois

Hello,
I am using last version mIRC 7.74 and older but I encountered the same problem:
Channels with +#voice shown in whois cannot be joined.




I think the problem lies in the conflict of these modes:

RFC2812 PREFIX=(ov)@+ CHANTYPES=#&!+ CHANLIMIT=#&!+:41
-
These are the IRCnet settings but I think other networks using the same daemon have the same problem.
Is there a way to solve this problem?
