One of my customer is encountering problems with Publicize for 3 weeks already, with 3 scheduled posts (correctly published on his blog but not on social networks). Indeed, even if enabled and configured correctly (at both blog and posts levels), it recently stopped working.
I host 2 of his blogs: http://www.lightzoomlumiere.fr and http://www.conceptionlumiere.com
These 2 blogs are set up with the same WordPress.org account. Can this be a problem?
The problem occurs with http://www.lightzoomlumiere.fr
I use Varnish on my server: is there something I should worry about? The feed is always "fresh".
Thanks for your help,
