I can't get create / edit family tree, no bottom . No matter what access i choose. This is a new installation of joomla 3.9.19

It is impossible to add a family no button, I modified the options, I allocated the access to admin as explained on your website. I made my tree directly on simbunch, saved the GEDCOM file but I can't download it to my joomla or add it to the family tree?
In your zip file to download also impossible to install, it does not work: app_simgenealogy

I bought your component 3 days ago and it is impossible to make it work
