We just released TubePress 3.1.2, which includes the primary fixes for Internet Explorer 8 and below. However, this version unfortunately does still not work with CloudFlare's Rocket Loader. We spent a good amount of time trying to diagnose the issue, but couldn't afford to continue to delay this release any longer.
Far from being dead, we are highly motivated to resolve the issue with Rocket Loader as TubePress uses CloudFlare's services extensively. To make sure nothing slips through the cracks, I've filed a bug report on GitHub. Feel free to "watch" that issue to track updates. I'll post updates there as I have them.
The workaround for now is to either disable Rocket Loader on your domain, or (and this is better) use a CloudFlare Page Rule to turn off Rocket Loader for any page on your site that uses TubePress.
@Eric - DId you receive my PM - I sent you all that you requested to take a closer look at this issue - please confirm. Much appreciated...
I did get your PMs. Thank you! And my apologies for not responding sooner. Since we have the capability to set up test pages with (and without) Rocket Loader, it's unlikely that I'll be using the credentials that you sent. Really appreciate the offer, though, and I very well might bug you again if testing on our side is insufficient.
Hope this makes sense. Feel free to ask questions if you have them! Thanks
