If you have ever edited a spreadsheet then editing your database is similar!
I am afraid to say that the only way we would ever directly edit a users database is after an assurance that a backup has been made and with a signed declaration – preferably on paper – that indemnifies us against any liability should something go wrong. This should also spell out the actions being undertaken.
On a more sensible level perhaps it is worth asking just what it is you are trying to achieve. I can understand, more or less, why you went back to WP 4.6 (although I am doubtful of it being helpful) but I fail to understand why you reverted Simple:Press to 5.7. This is certainly not something we would have suggested or even recommended. Version 5.7.1 was released very quickly simply because we had a small error in special forum ranks that was fixed. It also added two new permissions to control the viewing of images and videos. And that was it. Apart from that it is identical to 5.7. So I really do not see that you have anything to gain by making this more difficult than it already is.
Our recommendation is that you put 5.7.1 back into the plugins folder and leave the database alone.
By the way – which hosting company do you use please? Is it by any chance WP Engine?
