WordPress Move imported data disappears from admin view

Following a WordPress Move export/import of another site’s data, it appears perfectly in the new site, however as soon as the site is accessed or something happens with the database (such a backup/export) it all goes missing from the administrator view.

The database seems to still have the data, since I can’t create items with the exact same Slug name, etc (it auto renames).

I am using the GeoPlaces v4 theme (latest beta) which uses custom taxonomy entries for Place and Events, and more importantly the plugin WPML which provides secondary language options. A lot of the spanish pages are still visible but the english ones are not.

There doesn’t seem to be any rhyme or reason of what does and doesn’t show up following subsequent database writes.

Any suggestions on how to make the invisible database information visible again would be helpful.

Other Notes:
Exporting and importing the data using the wordpress exporter/importer says that the data exists already for any of the page data that’s “missing” from the back end.

I’ve attempted to export the original database from phpMyAdmin however the hosting provider has some issues with exporting the content. I’ve sent a support ticket to them to try and get the database exported.

Signs point to some sort of corruption on the database, however MySQL in CPanel shows all the data to be okay.
