Upgrade from 1.8.2 to 1.8.11 fails

I wanted to upgrade a xibo Installation from 1.8.2 to 1.8.11.

I make a Login and the upgrade site appears:
with Mozilla there is no Reaktion on klick the start button, i Switch to IE and upgrade Begins

at about Point 50 there are severe Errors in creating new colums, so i had to break this upgade.

xibo database is destroyed, so i could not go back to 1.8.2 without restore the whole xampp Folder (dont know which files were changed or modified)

now xibo 1.8.2 runs again.

Thank you for the information you have provided. Can you confirm the error messages that you are receiving? This will help to understand what is causing the issue.

Many Thanks.


a few minutes ago i tried to upgrade from 1.8.2.to 1.8.9 hoping that after this my upgrade from 1.8.9. to 1.8.11 will work.
at point 13 …1050 Table “lktagdisplaygroup” already exists

this error is similar to the errors i got in 1.8.2.to 1.8.11. Seems the upgrade procedute tries to do some things that are already one earlier.

Restoring my xampp with 1.8.2. works again, but I would like tu be always in the newest version.
