Hi there,
Im using ABMaterial to create web, running on my raspberry server.
I'm Trying to upload file from my laptop to server using ABMupload component, i only following tutorial on ABM website.
but somehow, the file is not uploaded.
here is my code. Btw in this code i'm using ABMupload and ABMFileInput. Both of that component have same problem (cannot upload to server )
