i’m apologize for not noticing there is a place like this…
maybe your problem have been resolved already, but i’ll presume you didn’t.
my best guess:
“this webpage is not available” mean you browser may check the setting “display friendly error”, which mean, this message mean nothing helpful at all.
so, you may update the plugin or uncheck the setting i’m talking about to see the really reason.
the url you get mean THE ERROR happened in open_callback function of QQ_CLASS.
hope that would help. thx:)
