Im only only trying to load the site up and i get internal server error 500, followed by after about 5 min the whole server seems to crash eg on the uptime status graph its offline. Other times its just extremely slow!
No i don't use cron jobs, the only mail part i use is MX Records so i can use my addon domain X-CREATIONS.co.nz in gmail.
Let me know if you need any other details to help with diagnostics.
