[SOLVED] Error trying to add a Project - by: pakkes

Hi,
I've installed Projeqtor 8.0.2 on a Apache 2.4 + Php 7.1.10 environment, on Windows 7 64bit. All ran as expected during installation and first setup.
However, I get an error while adding a new Project. The log tells that ...
2019-05-13 00:39:11.747 ***** ERROR ***** [V8.0.2] ERROR *****
2019-05-13 00:39:11.749 ***** ERROR ***** [V8.0.2] on file 'C:\Apache-2.4\htdocs\projeqtor\model\persistence\SqlElement.php' at line (2732)
2019-05-13 00:39:11.750 ***** ERROR ***** [V8.0.2] cause = Event::__construct() expects at least 4 parameters, 0 given
Any suggestion on how to avoid this error?
I first tried to use the 7.4.4 version of Projeqtor and getting the same exact error, so I moved to 8.0.2 ... same result.
Many thanks in advance for your help.
Regards
