Hi,

Has anyone found a solution for this?  We are experiencing the same issue 
with 2.22.5 and storing the session in the db. 
As a work-around, we have removed the ".isoformat" from the line 1247 of 
the gluon\globals.py:

modified_datetime=request.now, #.isoformat(),

What would be the impact of our work-around?  If we put isoformat in 
comment, the modified_datetime will be a string instead of a datetime 
object.
