Yeah it’s definitely the theme, and your solution worked for me too – thanks!
Will submit a ticket to the theme creator.

Yeah, according to Jetpack support:

“…there is a JavaScript error seemingly caused by a jQuery conflict. WordPress 4.5 bumped the version of jQuery so my best guess at the moment is that you have another plugin or your theme that is throwing the error which is breaking the Jetpack Carousel JavaScript.

If you could try and deactivate your plugins one by one till the problem is fixed that would be really helpful.”

At this point I suspect it’s the theme, as I already tried disabling all other plugins… I will play around with it, and try your solution too.

Yes, noticed that too.

This is caused simply by the size of the code sample. I started running into the same issue after 2.4.1 – code beyond a certain length yields a blank page. Smaller chunks of code still work fine (you can confirm this by trying to use a small section of this code).

I don’t know, must be a memory-management issue or something along those lines. There’s no feedback or acknowledgement, one can only hope that it will be fixed at some point, as the plugin is currently useless.

I’m experiencing the same issue: pages with longer code-chunks appear as blank white pages / fail to load. Pages with shorter code-blocks are still fine.
