sakulmore, 'blank_page' should be named 'index' as advised elsewhere.
Otherwise all your assets are being published to a blank_page_htm_files folder.
This is why Xara advises a blank index is kept, especially for PHP sites as your server is expecting to find index.htm, index, html or index.php and blank-page.htm is unknown, unless you have changed server configuration too.
In editing the NabBar, untick Site Navigation Bar and then double-click Button and Menu entry and type in your required Button Text.
Once added, these should not change, even if you retick Site Navigation Bar.
It will help you to click the Edit > NavBar > Help button and read https://helpandsupport.xara.com/xara...ation_bar.html and its "Normally you will want to immediately edit this new label in the NavBar dialog" to make sense of why you have had these problems.
