Just downloaded version 0.9, and get the following in my log:
WUnderground Error Error in plugin execution runConcurrentThread:
Traceback (most recent call last):
File "plugin.py", line 2001, in runConcurrentThread
File "plugin.py", line 306, in callDay
<type 'exceptions.ValueError'>: invalid literal for int() with base 10: ''
WUnderground Error plugin runConcurrentThread function returned or failed (will attempt again in 10 seconds)
Any ideas?
