I have tried iPage, but its not compatible with the platform phpVMS is based on, at least that’s how they explained it.
Well, the developer of phpVMS also offers hosting, so I would bet that it will work with phpVMS. See the “hosting from vmshost.io” forum in Control Tower here on these forums.
Other options are available as well. Are you planning to use phpVMS v7 or another version?
phpVMS v7
For phpVMS v7 check the requirements - http://docs.phpvms.net/
