Hey,
Thank for your response. I see that Theory.cern is using an older version of the indico feeds and events and both aren’t compatible with the current version of drupal surfacing the infrastructure. Refer to the Screenshot here :
Maybe it is due to the compatibility that is causing this unusual and abnormal functionality of the module. Here I’m attaching a link to a previous thread that my colleague updated regarding the unstable behaviour of the module Indico Feeds Issue
Also in the meantime I will look into a clone of your website to further investigate the issue causing concern to the functionality.
I hope this helps and in case of more clarification you can write us back here.
Regards,
Prakhar
