we experiment some problem on our dev install.
So we migrated the version 6 to last version 7
On front it is good we experimented some problem with form but after modifying some items in form and save it, it started working.
Now in backend when we try to edit an event we have the following error :
Error: 0 Call to undefined method MatukioHelperEvents::getCategoryListArray()
Video of the problem :
Error in console :
Any idea ?
