Well, I just use a VPS with 1G RAM - 1 Core - 20GB… Just for personal sites… *I dont think thats the problem the first time I added the website it worked for a few hours like the site for panel access after that I just get 503…
Turned on PHP errors readded the website and this is what I got from the error.log in /usr/local/lsws/logs/
