Base table or view not found

I cannot upgrade to 3.4.1. The update webpage skips Initialize and Back Up, so I can’t click one of those. The Download completes okay. The Perform Update starts but never finishes. I found the php_errorlog which says:

[12-Apr-2019 18:28:56 CST6CDT] PHP Fatal error: Uncaught PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘collinc9_phpl479.phplist_config’ doesn’t exist in /home/collinc9/public_html/lists/updater/index.php:319

Stack trace:

#0 /home/collinc9/public_html/lists/updater/index.php(319): PDO->prepare(‘SELECT * FROM p…’)

#1 /home/collinc9/public_html/lists/updater/index.php(807): updater->addMaintenanceMode()

#2 {main}

thrown in /home/collinc9/public_html/lists/updater/index.php on line 319

I would appreciate some help please.

@rcarver48 Looks like you’re using a custom database table prefix, and that this is not being recognised by a script. Have you set this in your config file correctly?: https://resources.phplist.com/system/config/table_prefix
