Apparently it's only that the page templates templates are locked, but that shouldn't prevent creation of pages, just prevent the templates from being vandalized.

Another possibility is that you seem to be using Visual Editor. Have you considered switching to one of the older editor options in your preferences? Visual Editor has been problematic in the past.
