Is it the beta v14.0.6.0 who have this bug! and, I did not take a backup before updating :-(

Henrik, that appears to be a shot of the online site. I assume the local preview is fine, so you should force a full upload rather than new and changed after a CTRL preview.

I have tried ALL, and nothing seems to work. All pages with products are emty - works fine i preview.
Try it yourself if you are in the beta program.

Henrik, I agree, there is nothing there, but it works on your PC so I suspect something is not being replaced on your host during the upload.

Try export to disk, navigate (windows explorer) to where you saved it and double click on it. This will open it with your default browser. If all content is there the site needs a full upload. I recently had to do this when one of my sites refused to do a full update, I used filezilla and removed everything on the host that I was about to upload by comparing the local list with the host list.

I managed to restore an older version of my project, so I am up and running again.

All files were updated....

Did you export from beta v14.0.6.0 to hard disk to see if all files were generated correctly?
