First congratulations very nice and useful mod!!
Well I installed this mod in my forum (phpbb2 Plus 1.52 2.0.19) and yes it is working, but only in the modcp_delete_posts pages, because in the viewtopic pages is not working when I choosed the posts(in the check box) in the topic and click in the Delete Posts button that is in the end of the topic nothing happens and I don't now why.
Like I said only I can delete posts when I click in the delete posts image and open the modcp_delete_posts pages so the viewtopic function is not working and I re-checked all the installation and everything is all right and also I uploaded the files for the mod.
Here if u want to take a look of my files.
I will wait your preciate help.
