Cannot read property 'css' of null

[col-panic]

Describe the bug
After upgrade the page often fails with Cannot read property 'css' of null showing. A simple reload
shows the correct page.

To Reproduce

1. Upgrade to newest version with existing page
2. Every page shows Cannot read property 'css' of null
3. Clear browser cache ...
4. Some pages show Cannot read property 'css' of null -> reloading the page in the browser solves the problem

Expected behavior
Every page should load without problems

I started seeing this after my upgrade as well.

Anytime I navigate to a page for the first time, I get the same above error page (Cannot read property 'css' of null). If I refresh that page, the page will load cleanly/successfully and will stay that way, even if I navigate away from that page and back.

But, if I ever bounce the wiki server/process, the issue will reappear again for the first load of markdown page. This only happens for the pages that I have created, not for system/admin pages.

I'm reverting to my pre-upgrade backup for now, but this was my setup:

• Docker images via docker-compose.
• Backend DB is a MariaDB container.

My upgrade path:

• From Wiki.js version (per admin dashboard): Wiki.js 2.4.105
• To Wiki.js version (per admin dashboard): Wiki.js 2.5.144

Docker Images via docker images command:

Hope this helps. And Thank you!
