Last week I've build a QuickCms website (most recent version) on my own PC using Xampp. After I finished building I uploaded all files to the webserver of my customer.
Because he added some extra pages to this website I decided to download the website to my PC again for backup.
When I run the site on my PC using Xampp I'm get a 404 error: no pages found. Admin is empty too, no files and no pages.
Never had problems with Open Solution websites. This is the first one with new database structure.
Check the data transfer type in your ftp client. Should be binary.
Check the headline (<? php exit; ?>) of the database files. Must have exactly 16 chars (with LF). Because by text transfer a CR char can be added after LF. And the "flatFiles-deserializer" starts to read behind the 16th char from database file and tries to create readable data (array) from the leftover. But if this rest begins with CR so you get error.
