[Resolved] JS error Cannot read property ‘concat’ making crashing my Divi blog

Hi Dominique-

Thanks for the question about W3 Total Cache and Divi.

It’s tough to say what might be causing that error. I tried to replicate it in our Divi testing environment, and I didn’t get the same behavior.

The only major thing I can spot on the front-end that is different from our testing environment is that you have Database Caching enabled. Can you try switching that off in Performance > General to see if the error persists?

Hi Dominique-

Thanks for giving that a shot! It’s tough to imagine what about Page Caching could be causing this, as far as I can tell you’re not minifying your JavaScript with W3 Total Cache. One other thing to try would be to switch your Page Caching method from Disk: Enhanced to Disk: Basic in your General Settings menu.

I’m going to do a little more research on our Divi testing environment and touch base with the development team to see if we can determine the cause of this for you. I’ll reply back here as soon as we have any news.
