Detective Work
So, I rolled up the sleeves and dug into the web server logs and the code of the CDN synchronizing tool. I found the GitHub site where the code came from, forked the code and created a branch with a couple of different attempts at fixing it. On my third attempt, seem to have a working hourly sync run using the WordPress pseudo-cron functionality. I’ll bundle up my changes and offer a pull request to the upstream developers so they can have the changes as well.
