I have this error in ispconfig log 02.11.2018-18:47 - DEBUG - Calling function 'check_phpini_changes' from plugin 'webserver_plugin' raised by action 'server_plugins_loaded'. 02.11.2018-18:47 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_lock Restore backup and Delete backup does not work.
That's no lock error, it's the exact opposite. Its a debug message that the server script works correctly. If you don't want to see debug messages in the log, set log level from debug to warning.
And in regard to your backup problem, the log output you posted does not contain any backup action. Are you sure that you disabled server.sh in cron first, then did a backup action like deleting or restoring a backup and then run the server.sh script?

The cron job lines you showed are active. If you debug by starting the jobs yourself, disable the cron jobs, for example by commenting them out. https://www.faqforge.com/linux/debugging-ispconfig-3-server-actions-in-case-of-a-failure/
