I got this message after the update
Unknown column 'dlevel' in 'where clause'
Which column is it?
I can confirm, just installed and got the same error:
Warning:
Unknown column 'dlevel' in 'where clause'
Pakket Update: Er is een fout opgetreden bij het installeren van een extensie: com_virtuemart.4.0.7.10744.zip
However, I installed the same package on another website yesterday and I can't remember having this warning. Both sites are J4.
This is known, and likely to be fixed in the next revision.
My solution here:
