Форуми / Cotonti / Extensions / ClassActive

Now my plugin doesn't work at all even without slots and tags (at production server), maybe the order should be the other way round? Hmmm.
I experimented with ordering and classactive had to have bigger priority in order to work at all (even when placed in header.tpl - slots and tags' bigger priority makes it disfunctional). It still doesn't work with slots and tags as well. If the priority was other way round, then slots and tags doesn't work. 

Haven't tested on localhost but on localhost it previously worked as expected. o_O
