I use Moodle 2.0.1 with Wiki in NWiki format.
For some wiki pages clicking on the history tab I get the error message:

Coding error detected, it must be fixed by a programmer: PHP catchable fatal error
More information about this error
Some pages in the same wiki display the history correctly.
Without the history I cannot grade student entries! So does anyone know what causes this strange error?
