I'm using Black Pearl 1.6.6, phpbb 3.0.9 and thanks for posts 1.3.1.
I did the installation correctly, without errors and the mod works perfectly in another template (pro silver). In the black pearl I can not see the icon to add/remove thanks, I can only see these icons in messages that have already thanks:
Something not right in viewtopic of the Black Pearl, what will?
Sorry my bad english.
