I need your help. I am new to Magento 2.3 and first everything worked perfect after the Installation on my Ubuntu 18.04 Maschine, but after my first Ubuntu restart the Magento Shop Page and Admin Page arent loading any more.
My first thought was that Apache or SQL are not running, but i checked and they have the status active. But Apache2 throws some errors (you can find them in the screenshot). Could this errors be the problem and if so, how can i solve them?
If you dont think that this errors are the problem, do you have any other idea?
I would be very releaved if you could help me with this problem, because I already wasted to much time and effort with this Problem and a proper Magento 2.3 Installation. Thanks a lot!
