hello, i can't get my forum 6.4.11 with php 7 to version 7.4 with php 8.1.
6.4 without extensions, standard design. PHP 7.4.33 is running,
with PHP 8.1 white browser content without error message.
Is there a solution for this, or can I upgrade the 6.4.11 version to 7.4 where PHP 7 is still running?
