I just went through the same thing, as was mentioned above make sure all of 
your plugins have been updated to the latest version. I had a few plugins 
that I no longer run as they hadn't been upgraded and after a look at the 
code the work to upgrade them was more than I was willing to tackle. 
WeeWX-WD for example (although someone has a work-in-progress repo where 
it's being worked on, but doesn't have any releases yet -- I did an install 
from a GitHub clone and it seems to be working so far).

At least for the two simple plugins I wrote I just had to change Queue to 
queue and replace urllib2 with urllib.request.
