it was a bad idea to use the vestacp backup and restore function.

unfortunately i believe you are better off restoring every domain by hand.

systemctl status apache2.service

Hint: Some lines were ellipsized, use -l to show in full.

by accident i realized (turn syntax:on in vim)

vim /home/admin/conf/web/apache2.conf

there was one missing:


at the very end of the file.

I made some changes in the vestacp backend and it seems to have screwed up the apache2.conf
