@Mayki You welcome,

Very well Then. One more thing, when doing manual update/upgrade, and this is from my experience, it's not like you press the Update button once and it's done. You gotto repeat the process a couple of times. and where we really see the process through, could it be /public_html/logs/upgrade.log

Sometime we overlook the little things.

PHP errors... Server PHP version and if not, the upgrade has not complete its full cycle yet, and looking at the type of error... the notification module is making a call probably to an upgraded instance/module or the other way round. (just check your notification but specifically its version)

Hi @Chris Andre Buys

I understand the "secrets" and "funs" with UNA.... I've been around since the Dolphin era...., but thank you anyway for your tips. I think I was able to find the problem and I will post the solution here, a bit later, just need to be sure if the mentioned PHP problem is gone for good.

Kind regards

Mayki

That is good news... ag, as long as you solved the issue and that is why I sounded so irritated perhaps, because I know the feelings of wanting answers quick from the forum.
