For Jumps (in my server)
some servers using this plugins:
multijump.amxx(2 jump) , purchasemod.amxx(pmodmenu +1 jump) , zm_vip.amxx(5 jumps)
you must write them in plugins.ini like this :
.............
zm_vip.amxx 
.............
multijump.amxx
.............

purchasemod.amxx
.............
or vips/nonvips will not get +5 jump or +2 jump

For parachute
if you are using :
purchasemod.amxx(buy parachute) , zp_parachute.amxx(parachute for all)
you must write them in plugins.ini like this :
.............

purchasemod.amxx

zp_parachute.amxx

For knockback
if you are using zp50 
zp_knife_menu_new.amxx
  zp50_addon_no_engine_knockback.amxx(disable engine knockback)
use zp_knife_menu_new.amxx before zp50_addon_no_engine_knockback.amxx
