I know this is improper bug reporting, so I apologize in advance...
Apparently one of my fellow guildmates is using a custom ui and was complaining that he couldn't click some of his buttons. He did some homework and found that, even though he disabled all the spamial-type messages from PvPLog, the PvPLog info box is still drawn and was getting in the way.
I'm not sure if it would be possible to remove the box entirely when someone disables the spam as opposed to simply leaving it and not writing to it?
And unfortunately this is all second-hand information for me, so I'm not even 100% sure I reported it correctly. Hopefully it will make sense though
