Hi Ciarán
I saw on twitter that all J4 templates now are ready to support the new child templates inroduced in Joomla 4.1. I have one site that runs J51_ nina, so I downloaded the actual vesion which should be 1.1.0 and did an update, that is, I installed the template over the old version. The thing is, it wrote things into /media/templates/site all right, however when I look into the backend, it still shows the old file structure and the button that now should be meant to create children would is still labelled 'create template copy' and clicking on it does not do anything. Also, nothing gets moved from the template folder to the media folder. That means, my custom.css still lives in /templates even though it still loads in the front end. Also, in the back end, when I go to system->side templates it shows no prewiew picture of the template.
When I install the same template on a fresh joomla install, everything seems to be just as intended.
Something seems very wrong with the way the update process works .Any suggestions on how to make this work?
