I get a blank screen on a website. The website first works fine but today it gives a blank screen.
I get the following error from the session_start (i removed the "@")
Fatal error: Cannot instantiate abstract class User in /home/verbindingsmaatlat.nl/public_html/new/contao-new/system/initialize.php on line 75
When i deleted the cookies in the browser the website works fine for the first time i load the page. But when refreshing the page wthe gives a blank screen!
Hop you can help me out!
