Hey. I found out why. I think you imported Posts in to your new website with some 3rd plugin or tool of wordpress. Anh the SQL Database structure is corrupt now. Sad to say.
Solution for me now that I have to remove & restore the wp_post at the time before import posts. That’s make my website works again & no error.
Hope you have your database backup. Or you have to export all post of your website. Delete all wp_post in database then re-import post again.
Hi.
I have a same problem as you are facing now. Just like you said, no luck at all. Are you using elementor builder or did something with the database SQL ?
I’m checking my website now hope I can find a way to fix this.
