wow. I just had this exact problem so I’m going post something here in case other people run to this.
Basically I wasn’t having issues with the plugin mentioned but this WAS caused by SOME plugin. I deleted every plugin in my folder and the site load up fine. Then I systematically added the ones that I still used one by one. I never really tracked down the faulty one, but since I didn’t use it anymore I didnt really care.
Thanks for the posts and updates guys.
actually nevermind, I found that just updating the timestamp to post the page but not on the front page was a better options for me anyways
oh and to clarify when I mean post previews I suppose I mean the post teasers on the front page.
