The thing is, looking at a backup of the dbase when things were working fine, there was no user_groups.MYI or page.MYI then either. There are a bunch of 'tables' that have only .frm files: page, pagelinks, revision, validate, user_groups. I honestly have no idea what a .frm file does by itself. Are these obsolete files leftover from upgrades? But then, why is the code looking for them?
Sounds like your ISP disabled InnoDB support, probably accidentally during an upgrade. Tell them to turn it back on.
