The edit page screen in Confluence is suddenly started looking deformed. What could be the reason? See screenshot.

The problem started occuring on upgraded Confluence instances. The problem is occurring in some of the spaces only. I have upgraded from 3.5.7 to 4.1.4. The screenshot shows how it looks

Do you have installed the subspace plugin?

If yes, please see https://studio.plugins.atlassian.com/browse/CSSP-78

[Pankaj Jangid]

Thanks this was the problem.

What browser are you using? If you are using Internet Explorer 7, you may want to read the following End of Support Announcement. See what browsers are supported with Confluence 4.x here.

[Remo Siegwart]

Strange, did you already try to clear the cache?

[Pankaj Jangid]

I am using Firefox 10.0

Also look for badly-formed html in the "custom html" section in confluence...

[Pankaj Jangid]

We have not added any custom HTML.

[Nic Brough [Adaptavist]]

+1 Remo's answer. Also, as a quick experiment (irrespective of browser), what happens if you increase the font size ("ctrl +" in Chrome and Firefox - I don't have an IE to hand to check if it's the same there)

[Pankaj Jangid]

No change in alignment. Zooms in/out with same alignment. :(

[Nic Brough [Adaptavist]]

Ah, ok, worth a shot.

[Robert Robert]

looks like a stylesheet problem

[Matthew J. Horn]

I agree with Robert's suggestion. This is most likely due to changes in stylesheets. Maybe you didn't add any custom CSS, but perhaps you either edited one of thte Confluence stylesheets or added a stylesheet import in the Custom HTML header.
