Davey, turns out the problem is in fact that you are using Windows. The resource, LOG_LOCAL0, is not available on Windows. The quickest fix will be for you to edit lt_functions.php, line 9, and change that symbol to LOG_INFO. I will pursue some server OS detection code to use LOG_LOCAL0 on Linux and LOG_INFO on Windows for the next release but can’t give an ETA for that version at the moment.
