Hi everyone, I developed this problem some weeks ago and I don’t know to solve it.
Whenever i access my website I see nothing but a white blank page, I asked some people who told me the issue is called White Screen of Death, but one of them told me he could only help with me paying him a few bucks and I believe its justs a minor issue i can fix myself with a little guide since I am a little broke.
So any help would be appreciated.
Thanks!
