Twitter timeline widget not functioning

Hi

I know there have been posts about this before, but none of the solutions offered work for me.

Basically I’m running the Customizr theme (with a child theme) and in my RH sidebar I’ve installed the twitter timeline (jetpack) widget. I’ve copied in the correct ID code, set up everything as it should be. But I can’t get it to work.

Whenever you click on a page with the sidebar on it, the heading always loads (i.e. in my case Follow Frank on Twitter). A panel BRIEFLY appears underneath showing my latest 3 tweets, but then it ALWAYS rapidly disappears again.

It may not be the widget itself that’s the problem, as I tried putting a text widget in the sidebar instead, and posting in the full twitter widget html code. But the same thing happened. The tweets briefly appear, then disappear. The craziest thing is, sometimes they appear for like a second or two, and sometimes it’s several seconds, but they always disappear.

I thought it might be to do with my browser settings, but the problem seems to be the same in Chrome or IE.

I’m not a coder or developer so I usually reply on widgets just working, or easy fixes for someone of my level. But I’m plumb out of ideas on this one. Does anyone else have any, or a similar problem? Be obliged if you could let me know.
