I am using Jevents on 16 different websites. In the control panel of each of these websites there was a notification "Update for extensions available" and "Installed = Jevents 3.4.10" and "Available = Jevents 3.5" and "URL-Details https://www.jevents.net/updates/-d3d3Lm ... 3.4.10.xml.

I installed the update and it said "Extension sucessfully installed". When I returned to the control panel the previous notification was there, indicating that there is an update from Jevents 3.4.10 to Jevents 3.5 available. Tu put it in a nutshell: the update does obviously not install.

Thank you.
