[Typo3] Field list error

[Dan Nguyen]

Hello;
In a sudden, I've got the following error when adding a plugin for a 
page content:

*Errors:*
	2: SQL error: 'Unknown column 'tx_sowAdmin_tx_sow_is_author' in 'field 
list'' (tt_content:NEW426e7f27eeb91)


It happens when any plugin is added.  I would appreciate very much if 
somebody can help with this.  It looks like there's a field list 
somewhere (which I need to look into?) with an extra entry in it.  As a 
matter of fact, the "Unknown column" in the error message never existed 
nor needed.

Thanks and regards,
