Upgrading Problem

[CS-Cart_team]

What was described in the initial post in this topic, were the server timeouts. Please refer to my answer here:

Upgrade 4.11.2 Multi vendor

It seems like server timeouts interrupt upgrade process. Please contact your server administrator and ask to increase the max_execution_time and memory_limit server PHP directives. Also if mysqldump is available at your server, you can set the value of the backup_db_mysqldump tweak in the config.local.php file to true: 'backup_db_mysqldump' => true, This will significantly speed up the backup process, but may not be supported by the server you are using.
