I had Kinsta restore file permissions. That allowed me to run the Start SEO data opt. This time the progress bar was visible while it processed. Yet the column was not visible or available to be selected as a screen option.
Went into phpmyadmin and found the values did exist on wp_yoast_indexable table. Disabled all plugins on Staging, cleared server and browser’s caches (I do this after every single change but in this case I think it’s important to highlight it) the columns was enabled and visible.
I reactivated the plugins one by one checking one by one if it affected that column. The answer was no. None of the plugins had any issues with Yoast whatsoever and the column remained visible.
Performed the same tasks in the Live site. It’s fixed.
I believe that for some reason I have found that The Events Calendar and Yoast have issues. When Yoast is updated, the event urls go 404. I found a fix for when this happens (but with Yoast updating every week, this becomes quite annoying so you may want to check into your compatibility with them as they are a pretty popular plugin as well – but this is not my business – up to you)
Anyway, I investigated, researched and tested (there were many other steps taken to figure this all out) and took care of it.
Leaving you the resolution just in case some other lost soul out there needs it.
Cheers!!
