UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support I have installed the 8.0.0 and I have a white page dashboard.php

Hello,

We just purchased the 1 year new licence for the v8.0.0, and after installation and all properly setup, we cannot configure further the forum, as we have a white page, selecting the CONTROL PANEL : https://www.finalemus.com/admin/dashboard.php

What could cause this ?

Thank you
