As @Faqole requested, I ask support here.
The plugin does not work on my platform.
That's what i did:
Activate the plugin;
Set only 1 exclusion in the plugin, for admin accounts (but no changes to what i wrote down here if I remove the exclusion);
Set a sub section of the forum with MAX limit 8000 characters (others limits set to 0);
Tried to insert a topic with 20000 character or so, no effects, topic successffully inserted;
While i was IN the topic, moderators setting do not work (tried to delete the topic, get error code QTE/1);
Was fine to delet the topic OUT of it, in the section screen;
While I was doing this tests, I saw (and other Staffer said to me) that Notification not work, every message inserted was successfully posted but invisible right after. We could communicate only trought private message;
The moment I disabled the plugin, all turns back to normal.
Today i tried to disable all other plugins and try this one with no interferences: same result.
As you see, I cant test so much or activate the plguin for long periods, cause my platform goes in chaos.
