Sry ... I'm not very expert in php but, the thing is I was trying to add some CSS attributes in the settings -> customize content header. And it seems that i messed up the content block and some injected css was breaking the rendering. Now my whole website is blank empty but "view source" gives this:

It feels like i commented out the other logic accidentally?

After the blank out, I went to database trying to remove the injected content in "settings" table by

update settings set value="" where setting_key="app-custom-head"

and it doesn't work either. Any place i should look into to revert the customized header change?

Thanks very much.

I was thinking about ... a direct API call to set the header content to be empty again or sth like that ... i don't wanna get my hands dirty with db again without some "official" guidance lol. Yeah my bad. thanks for the help.

Hi @wx-Yao,
The /settings page specifically does not load in the customizations so that nothing breaks and you are able to revert changes where needed.

You should still be able to visit <your_bookstack_url>/settings so that you can undo the changes.

Just realised you mentioned running the sql query. Settings are also cached so you might have cleared the setting but it's still in the system cache.

You can try running php artisan cache:clear to clear the cache. Might have to run with sudo depending on permissions.
