I am having the same issue and have checked all of the recommended suggestions per this thread and the linked thread. I contacted my host and they did not see anything out of the ordinary on the server side. I have multiple feeds, and sporadically, the posts will not sync. One feed in particular I am having trouble with. I disconnected/reconnected, took off the image setting, and still no posts will pull. Is there a way to access more detailed debugging/error log information related to the plugin? I am also willing to upgrade to the premium version of the plugin if for some reason this would fix the issue, but need to figure out what is causing the issue. Thank you!
