Issue first install in v9.0.0.

Hi,

I am totally new in Projeqtor and I'm trying to install the last RC 9.0.0 for my job.
I work with wamp on Php 7.1.16 and MySQL 5.7.21.
The configuration seems to be done, but i can't connect with default admin/admin.
I allways have this message : "ERROR : Une erreur est survenue le 2020-12-28 à 17:32:21"

I don't understand where I did a mistake ?

Tanks a lot,
Jeff.

Thanks for your answer.
I think I found the problem. I change the max_execution_time from 120 to 1200, and it's ok now !

I can start my configuration !
