I use txadmin web-service cuz I host the server locally.
I start all my resources from there and they usually work.
The console log doesn’t give any errors neither.
My fxmanifest.lus file does get picked-up by txadmin and goes like this:

fx_version ‘cerulean’
games {‘gta5’}

name ‘test script’
description ‘marker test script’
version ‘v1.0’

client_script ‘test_client.lua’

What is above might be wrong cuz I wrote it on my phone but that’s basically what is in it.
