Hi,
I get errors every now and then and it stops the generation of graphs.
May 8 08:00:20 jed164 weewx[10989]: manager: Daily summary version is 2.0

Today I had it appear 3 times so there is "something" that makes it appear.
This is what is around line 1005:
mainMethNameAttr = '_mainCheetahMethod_for_'+concreteTemplateClass.__name__
mainMethName = getattr(concreteTemplateClass, mainMethNameAttr,
None)
if mainMethName:
def __str__(self):
rc = getattr(self, mainMethName)()
if isinstance(rc, unicode):
return rc.encode('utf-8')
return rc
def __unicode__(self):
return getattr(self, mainMethName)()
I don't know anything about python.
If anyone knows what this is that would be great.
Thanks
