The current program works and also the blog function, at least for me there are no problems with the blog.

Reinstall WebSiteX5, click on the user name at the top right and select “My Profile”, the program can be downloaded here and the license key can also be found here.

The home.html file is normally created when the intro page is activated. If necessary, deactivate the intro page and, with WebSiteX5, delete the two files home.html and index.php in the FTP window.
