Hi, Thank you for your quick reply!
Yes, the feed works on the simplepie.org demo page. It’s also working on my other virtual machines just fine. I’ve checked the nodes in the web farm and the php.ini files have the following setting:
allow_url_fopen = On
The issue seems to be localized to the fact that the plugin and WordPress files are hosted on a remote/shared drive and not directly on the nodes running IIS. Is there anything related to permissions that might need to be set for a service account to create temporary files in some directory?
Thanks again!
