What errors are in your Tbird Activity Manager?  Those may be helpful.

Note that the auto update for 3.1.6 was just a day or two ago.  Is the
update a factor or merely coincidence?  Upgrading a server component as
client component simultaneously is a recipe for disaster WRT
troubleshooting problems: the proverbial finger pointing.
