I've got a vBulletin forum running a script to generate Google XML sitemaps and it runs fine using the "run now" button, however... On timed runs it is being called (I can see that in the logs) but the files aren't being created. This indicates that the owner of the folder/files is changing somehow between the manual run and the cron run. If I delete the existing files and allow the schedule to call the script the files don't get recreated. Any one know what this might be? thanks
