Fatal Error Occurred Error on \core\vb\library\node.php : 808 Script: 500a1 Step: 142

During upgrade from 4.2.3 to 5.2.0 I receive the following error.
Fatal Error Occurred
Error on \core\vb\library\node.php : 808

Script: 500a1
Step: 142


Any help would be appreciated.

Read through some other threads and set my database to UTF8 encoding. Seems to have fixed the problem. Does anyone know the cause of this issue?

Now I'm receiving this error
Fatal Error Occurred
Error on C:\inetpub\wwwroot\newforum\core\vb\library\style.php : 548

Step: 2

Seems to have fixed after a hard refresh of the page.

Now getting this.
