Hi,

I'm trying to upgrade from 4.2.5 to 5.4.3
However during the upgrade process i get this error:

500a1 Step #142 Fatal Error Occurred

Error No permissions on node id 27 on /var/www/oldforums/core/vb5/route/channel.php : 23

Script: 500a1
Step: 142
What should i do? I have no idea where to look
