I have a little problem, when I publish a post without a featured image on my Zoho - WordPress Grid Portfolio , the content of the post appears twice, one is full width and the second one with the sidebar on the right as I wish it would be. I have the same problem when I create an event with the All-In-One Event Calendar plugin, the content is duplicated as you can see in those two example pages :
1) a post without featured image
2) an event
Thanks in advance for your help!
