Hi Tony
Thank you for responding.
I made a fresh Joomla 4 installation and then installed Jevents. Then I imported an iCal file from a calendar from a live website and that went fine. I can see the events and all the categories were imported as well. Cool.
Then I tried to make a new event and this I cannot do.
Another site where I am testing Jevents with joomla 4 is the site below. This site is a copy of a live site which has been successfully upgraded to Joomla 4. It has not had Jevents before but, as a test-site, I thought to try Jevents, so I made a fresh install of jevents. Here the problems are different. I cannot make a new calendar, and I cannot enter into the management of categories, but I can make an event(!).
I added site logins in the private description field.
Thanks in advance
