Many hosting providers will not allow apps like WE apps to run on a regular hosting plan as these apps might use too much RAM/CPU/IO on the server and bring it down on its knees.
We apps are recommended to run in a VPS (Virtual Private Server). This is a server you have total control of your self. Install what you want, run what you want etc.
You’ll have to set it up your self though.
Install the ia32-libs for example if it’s a 64bit server.
