I dont like hosts that try to blame other factors, and try to refuse to fix a problem with their own service. They should be trying to do everything they can to help you. My host letshost.ie, I find the best. I had a problem with my phpvms install (it was caused by me unintentionally, and did not know at the time) I asked for help, I was getting no errors, just a blank screen. PHP was not the problem, and neither was the database, as the forum which runs on php and the same DB as my phpvms install were working fine. I ask them, they said it was to do with some sort config error or something cant remember fully. But when I asked could they help me, they said it was not usually done as it is outside my support area for my plan. But they said they would have a look into it for me. I find if a host is willing to help even if it is not supposed to be done, a very good host.
