@Gene Steinberg You may have noted that we first posted on this thread on the 16/9/2019, so there doesn't appear to be any valid reason to
leave it really.
As stated previously,
"...It's a forum. You can express your own frustration / views as much as you wish..."
That still applies (fortunately for some) even if this amounts to nothing more than bombastic, blustering, self-focused, twaddle.
Meantime, back on to the topic of problem resolution.
For the benefit of other forum users, specifically, those Plesk Obsidian users who may have inadvertently (or by choice) upgraded to MariaDB 10.4.* (unsupported by Plesk at the time of this post) we're sure it would be much appreciated, if, you could post your own, chosen method of successful resolution and then your subsequent, confirmed successful use of Plesk Obsidian running on Maria DB 10.4.* too. Unless... those specific details are posted by
another user in advance. You've disregarded all of our contributions so far (which is absolutely fine - it's a forum
after all ) so obviously, it can't be us that make that detailed post now.
