Could it be due to the Smush plugin I’m using?
To find out, try disabling all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
If you can install plugins, install and activate “Health Check”: https://wordpress.org/plugins/health-check/
It will add some additional feature under create a new menu position Tools > Site Health.
On its troubleshooting tab, you can Enable Troubleshooting Mode. This will disable all plugins, switch to a standard WordPress theme (if available), allow you to turn your plugins on and off and switch between themes, without affecting normal visitors to your site. This allows you to test for various compatibility issues.
There’s a more detailed description about how to use the Health Check plugin and its Troubleshooting Mode at https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/
I can see the video on the front page when I visited your website.
As mentioned above, the best way to test if there is a plugin causing a problem is to disable (or even delete and install one plugin at a time) all plugins and enable them one at a time.
I can see the video on the font page. If you don’t see it, also check your server side caching. I found some hosting providers have server side caching causing these types of problems.
I deactivated smush. It works fine now 😀 thank you.
