JInstaller: :Installeren: ErrorSQL Unknown column 'attribs' in 'XXXXX_jem_venues

Hi I am getting a warning during the installation of JEM. I upgraded Joomla (did not deinstall JEM).

Warning:
JInstaller: :Installeren: Fout SQL Unknown column 'attribs' in 'XXXXX_jem_venues'
Extension installation stopped.
Pakket Update: Er deed zich een fout voor tijdens het installeren van een extensie: com_

I can see that the column does exist.

i think a database error. Can you give me some advice?

Please give more informations: from which joomla to which. Which JEM version. Did you follow the instruchtion for Update joompa and JEM?

hi, thank you for you message. I have upgraded from Joomla 3 to 4 to 5. Than i installed the latest version or JEM 4.2.0

Doei Foeke,

please, never expose the prefix of your database. The prefix is an additional security measure.
I changed it to XXXXX in the subject and in the text.

If you had searched in our forum, you might have seen others with the same problem, when they did not follow the exact update steps provided.
Maybe e.g. this will help: www.joomlaeventmanager.net/forum/bugs/12387-1054-unknown-column-places-in-field-list?start=6#30615

Succes ermee!
