I can't add media or links to post

For the past couple days I’ve been having problems in my dashboard when writing up a new post. I can’t add a hyperlink using the Visual Editor. Plus, I can’t add any Media.

I’ve read through the related topics here with the same issues but can’t seem to resolve mine using those tips. I’ve deactivate all plug-ins and had the same issue. I’ve added this coding to my config-wp file: define(‘CONCATENATE_SCRIPTS’, false );

So far nothing has worked… do you have any suggestions? I’m using the Tempera theme with the current version of WP. I did update a couple plug-ins recently but can’t remember what ones. Since I deactivates all and still had the same issue, I don’t know if that matters.

Not that it matters, but my website with the issue is https://www.RedBeansAndEric.com.

Thank you!

Eric
