I was working on my site and it built fine
| LANGUAGES | EN | DE
-------------------+-----------+-----+------
Pages | 62 | 331 | 46
Paginator pages | 0 | 8 | 0
Non-page files | 1 | 22 | 1
Static files | 117 | 117 | 117
Processed images | 0 | 118 | 0
Aliases | 13 | 16 | 2
Sitemaps | 2 | 1 | 1
Cleaned | 0 | 0 | 0
Suddenly the build result is different
| LANGUAGES | EN | DE
-------------------+-----------+-----+------
Pages | 12 | 1 | 1
Paginator pages | 0 | 0 | 0
Non-page files | 0 | 0 | 0
Static files | 117 | 117 | 117
Processed images | 0 | 0 | 0
Aliases | 2 | 0 | 0
Sitemaps | 2 | 1 | 1
Cleaned | 0 | 0 | 0
Now there is an empty site
There are no obvious changes which explains that behaviour to me
Any hint?
