My new installation isn’t working after all. Some posts work some other don’t. The ones that work always do, the ones that don’t they never do.
In my case it can’t be load because the site has not launched yet, although I have a godaddy.com hosting, not sure how they handle load in shared servers
Fixed by reinstalling wordpress from scratch. My guess is that one of the several “social sharing” plugins I tested messed something up.
