[Plugin: Quick Post Widget] Widget not showing up on page after installing W3 Total Cache

I installed, activated and de-activated the W3 Total Cache and it seems to interfere with the plugin. I also now started using the CloudFlare CDN network (signed up with them) and I think it interferes with the page the widget is supposed to show up on because sometimes it shows everything BUT the content input box and sometimes it shows everything right. But now it doesn’t show it at all.

Hope you can help me fix this. Thanks.
