Why doesn’t the barrier have afterburners?
(OP)
I can’t find any answers as to why the harrier doesn’t have after burner whilst all most other front line fighters did.

Edit: Nope, sorry, a central jet was one of the initial concepts. Reading further, the P.1154 used vectored reheat for the multirole VTOL airframe.
Consider that reheat is not used on a number of front line attack aircraft: A-4, A-7, SU-25, A-6, A-10... . Probably if they can but they don't then it's a matter of mission design/requirement.

Note that afterburner fuel burn is absurdly high; an F-16 purportedly burns 64,000 lb/hr of fuel in afterburner mode, compared to 8,000 lb/hr at full throttle.

RE: Why doesn’t the barrier have afterburners?
Harriers have a relatively high by-pass fan-engine... the small core engine drives the large fan section which supplies the majority of it's thrust to the forward-2-swivel nozzles... and the core engine thrust, and some by-pass air, goes to the aft-2-swivel nozzles. Also, core-engine compressor-section compressed/hot bleed-air is 'pumped' thru Inconel tubing to the wing-tips, aft fuselage and nose for reaction controls in hover/slow-flight.
WAG on my part... for short take-offs... in addition to swivel-nozzle thrust/lift movements... bleed-air may be 'blown-over the flaps' for increased lift-effectiveness at slow speeds.
In-other-words… every bit of thrust/power is extracted thru the [4] swivel nozzles... making afterburning infeasible.

I hear it all the time, take it easy on 'em.

I guess as the Harrier is only subsonic the cost benefit didn't work plus it appears to greatly increase exhaust gas temperatures which appears to present all sorts of operational issues (anyone found a pic of a F35B operating out of a forest yet?).
