My sites 404 page is not regenerating when I delete it. I'm new to silverstripe, so I could be wrong expecting this behavior, but I was under the impression that the 404 error page (along with the rest of the sites pages) was cached. I found the file (assets/error-404.html) and removed it. But now all I see is the silverstripe error page. If I do this on my dev, I see my 404 page, but it does not get recreated. What gives?

btw - the search on this forum sucks. just my two cents :)

Have you tried republishing the 404 page in the CMS? (this is what regenerates it). If that doesn't work you might want to check that the assets folder is writable.

Ah, that's what did it, thanks. I assumed it was the request for the page that caused it to generate.

I recently moved my website and was wondering why my 404's didn't work... obviously I needed to republish my 'page not found' page but maybe this should be automated. I found it particularly confusing as I actually got the right 404 but the links to the css were wrong so it was not formatted.

Would it be nice if dev/build generated missing 404 pages?

Just a thought

I'm running SS 3.1 and also can't get 404 page to regenerate. Permissions are ok and publishing doesn't help. This is really strange: the 500 error page regenerates correctly when republishing, but the 400 error page gets empty. The file contains nothing after republishing.

Also I don't think it's a good habit to require republishing these pages. Shouldn't ?flush=all do the job? Thanks :).

Also check your ErrorPage table (and _live) ... I had multiple 404s in there so deleted all and a publish fixed it for me
