That's very strange, as well as the fact there are no errors in logs. There must be something, at least. Do you see messages signifying successful initialization of your script in `oxauth_script.log` each time you update it? If you can see those, but no errors during runtime, while it doesn't produce the expected result, you should try debugging your script, by putting lines like this
```
print "Debugging insert #1"
```
...all over it, to find sections where it fails. Covering it in "catch-all" try blocks may help as well:
```
...
import sys
...
try:
...
some block of code
...
except Exception, ex:
print "Catching point #1"
print "Unexpected error:", ex
raise
except:
print "Catching point #2"
print "Unexpected error:", sys.exc_info()[0]
raise
```
