I had same problem and I had to uninstall everything.
Now I’m trying it on a fresh pc the versions of XAMPP and WP made by Bitnami, but also those look like there is something not clear… same problem for downloadinbg themes or plugins. Bitnami made a new path for WP, and XAMPP doesn’t knows it at all.
Normally it should be /opt/lampp/htdocs
but with Bitnami installation it becomes /opt/apps/wordpress/htdocs/
and this makes the difference in many other paths. How can this be an automated installation if it doesn’t see paths and/or links to them?
They should erase that word of “easier”.
