I can’t open the different categories. The Component List is disabled if I click at one category. I have tried to reload the K.Creator but it is also not working. Don’t know what happens.
I am using Safari and I am actually not able to try it with Chrome or else
Try clearing Cache, History.
Or Go with incognito or private browsing mode.
Check your internet connection.
Or, the latest option, delete and re-install browser.
