mysql error 1356 references invalid table(s) or column(s) or function(s) or definer/invoker of view

Long story short, I recovered a mysql backup from my old LAMP server and afterwards I kept getting a view error when editing users. After many hours of trying to find a fix I was about to dump and rebuild the mysql.user schema since it was what was messed up since it had old user rights and everything from my old server. I googled for hours and hours trying to fix it finally what did it was one simple command….

mysql_upgrade --force

boom user view worked
boom I can edit and add users again through the webmin interface.
Thanks for reading hope this helped!

Duplicati showing error after every run

The issue is that duplicati does not have access to locked files such as excel spreadsheets or other items locked by the programs that open them. the fix is super easy and only two steps.

Step 1.

  • Open Duplicati ui, and go to the backup under Configuration: choose Edit



  • Then go to option 5 “Options”

  • Under advanced options, click the down arrow then click “add advanced option” and scroll down to “snapshot-policy”
  • select it, then change the off to on in the drop down box, then save your settings.
    it should look like this.

 

  • Step2.
  • Right click Duplicati from the system tray icon, and select quit.
  • Goto the C:\Program Files\Duplicati 2\
  • right click “Duplicati.GUI.TrayIcon.exe” and under the compatibility tab select “run this program as an administrator”


Re launch duplicati !

All done! Run the backup again to verify it worked and that should be it.
