[nag] Task list display - warning messages

[Alastair Davies]

Using Webmail Edition 1.2.5, and Tasks (nag) H3 (2.3.4), I get the 
following warning messages in the display "My Tasks".  The warnings 
appear above the actual list of tasks, which are themselves listed 
correctly.  Could this be a configuration problem, or a database 
problem?  I am using MySQL. 

Many thanks for any suggestions.

Kind regards,
Alastair
