[TYPO3] Modern FAQ (irfaq) installation problem on 4.1

[Ignatius Reilly]

Hi,

attempted to install Modern FAQ (irfaq) on Typo3 4.1; followed the doc 
by the book.

Now the web page shows:
NO entry in the $TCA-array for the table "tx_irfaq_q". This means that 
the function enableFields() is called with an invalid table name as 
argument.

The entries have been correctly created in the extension's tables.

Any idea anyone?

Thanks
