Nation - video background not working


we bought Nation theme but video background is not working: user: falcon password: tecob0916

Could you please correct that?

Best regards


Did you mean the video in the slider or block video background?


This one is the faulty one:

You can access going via

"Home => OnePage Versions => Background Video"

I see it's working well. Please check the screenshot:


it does not work on Firefox and Chromium, and I got this javascript errors:

TypeError: Cannot read property '1' of null /modules/drupalexp/modules/dexp_block_settings/assets/js/jquery.mb.YTPlayer.src.js?qhitu4:2078

TypeError: Cannot read property 'get' of undefined /core/misc/drupal.js?v=8.9.6:13

there's somethiong wrong. On my computer's customer also the videos are not played. What can be wrong?



In your demo I have the same problem:

The error here is:

TypeError: Cannot read property '1' of null /8/nation/sites/default/files/js/js_fr_DkNQGQph5Alnj8k60SNJjaO-oxC8E71xHsg9JyU4.js:389

there's something in your theme that prevents it from viewing this background video


What is chrome version your are using. I checked on Chrome 84.0.4147.89 and Firefox 81.0 but did not see any error in the console.


I'm using Chrome 85.0.4183.121 and Firefox 81.0.1 all under ArchLinux. I will create a new subdomain: and will upload the default website drupal 8 from your demo, with no updates and touching nothing and we'll see if it works. I get back to you soon (today I hope)

Best regards


I have installed It's exactly your demo with no updates and nothing modified. I have the same error on Chromium:

TypeError: Cannot read property '1' of null /modules/drupalexp/modules/dexp_block_settings/assets/js/jquery.mb.YTPlayer.src.js?qf91m9:2078

TypeError: Cannot read property 'get' of undefined /core/misc/drupal.js?v=8.9.3:13

There's something wrong...


I found the problem!

It's explained here:

the problem is with OS detection on YTplayer library. I updated it to the last one on and it works fine!

You should release an update as all users with GNU/Linux will have this problem.

Best regards,


Thank you for your updates. We will update it in the next release.

Best regards.
