I could confirm the issue on your shared website.
This can be due to plugin conflict on your site so please try temporarily deactivating all plugins except Unyson plugin and WpBakery page builder plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Could you please tell me in what format you have added the video in the video field?
Would you mind if I log in to your site and do some troubleshooting? If this is ok then could you please temporarily share me your site admin login details privately by adding them in the box having text “Enter your private content here (only you and forum moderators will be able to see it)”?
Please don’t share sensitive information on the forum as this is a public forum so the information shared can be seen by others.
Please change the shared credentials ASAP.
If you want to share anything privately then you can do so by adding them in the box having text “Enter your private content here (only you and forum moderators will be able see it)”.
