After yesterday’s update categories are not visible anymore and I cannot edit existing galeries.
A new Galery can be created and edited.
Could this be an update (conversion) issue?
Example page http://www.winkeltjes.net/winkelstraat/ (no categories visible above picures)
Also a backup from a week below has not solved the problem. Please reply to my question shortly, I have ordered a pro licence to get this kind of support.
