Hi @j3br, Sorry to hear you are facing issues. Did this issue appear after an upgrade or is this a fresh installation?

Could you try running the following commands from the BookStack folder:

php artisan cache:clear
php artisan view:clear

Hi,
I noticed the issue after rebooting the server following some OS patching. The BookStack installation is a few months old.
I ran the commands you provided but I still receive the same error messages.

HI @j3br, Sorry for my late reply. I can only think to suggest running the commands again with admin privileges (via sudo if on a linux/mac system).

I believe the old cached views are being used which are outdated after updating. After running the commands you should not have any files within the storage/framework/views folder (Which are shown in the above log).

I decided to just reinstall Bookstack. It seems to work as it should now.
