Since updating from version 3.7.15 to version 3.8.0, as soon as I edit a module, it is "cleaned up" and there is nothing in it of anything I could have done before , just as it does not recover any more JSON backups that I had been able to make.

My mistake, I think, is that I didn't read the SPB documentation BEFORE :-) the update because it is clearly stated on it that SPB 3.8.0 does not work with PHP 8 and MySQL 8 .... except that I am using a MySQL version 8 ....

So, question: how do you reasonably revert from version 3.8.0 to version 3.7.15 so that all of that is back in place and that it works normally ?
