For me, it was auto-increment and primary key issue at the time of DB import. Yoast SEO plugin used “utf8mb4_unicode_520_ci” collate, which was not supported on my new server. I edited the SQL backup and replace “utf8mb4_unicode_520_ci” with “utf8mb4_unicode_ci” and imported on the new server. And it worked perfectly fine.
Hope this helps.

Hi @ianharmon,
I had exactly the same issue and found a fix. What worked for me was “run PHP as” setting in “PHP Settings” on plesk server. Its value was “FPM application served by Apache“. I changed it to “CGI/FastCGI application served by Apache” and the plugin started working very well.
Hope it helps.
Thanks!
