Blank screen
There's a few situations that seem to cause blank pages from WordPress. It doesn't seem like the request wasn't received. Instead, it seems like there's no HTML sent. Or maybe it's a redirect response that doesn't make it to the browser.
Investigate blank screen for:
- [ ] Installing a new plugin from the admin
- [ ] Importing XML
- [ ] Core update
Created and destroyed a DO droplet a few times to try reproducing the issue. So far, I've seen it once. Couldn't see anything wrong from the nginx side. Forgot to turn on varnishlog.
The only time I've seen this was with the simple-fields plugin. It was causing a white screen (and only on my production box, not staging) when it called it's internal clear_cache function. Wasn't a plugin conflict, it would do this even if it was the only plugin installed.
I opened a support ticket with the plugin's author to see if they would comment: https://wordpress.org/support/topic/clear_caches-causing-wsod?replies=1
@carlalexander I get this with any plugin install. Happy to give you ssh access to do your thing and check the logs
If you're getting this every time, that'd be great. I'm a bit busy this week because I'm speaking at WordCamp Toronto next weekend. I'll reach out over Twitter to get the details.
It seams that the install process of plugins is completed correctly, despite blank screen.
Yes, that's the issue I observed as well. My hunch is that it's a bug inside the Varnish configuration. Something gets cached and we get that back instead of the redirect. It's just hard to reproduce.
Ran into a similar issue today doing tests for #29.
Couldn't get the /wp-login screen to display with Varnish. Turning off the Varnish server and going to the direct PHP fallback worked. Since I could reproduce the issue consistently, I managed to get some log output. This is from a forced refresh of the page.

The big thing that stands out is the content length. Everything on the Varnish side says that it's 0. That said, the access log from PHP shows a content length of 1144. I haven't been able to find anything on that, but this seems quite bizarre.
The only thing that's weird with this is that I only reproduced this using the 4.1 version. Reverting back to 4.0 fixed the issue it seems. Anyways, this might give us a bit of an idea of what's going on.
I haven't had this issue happen in the past two month during testing other PRs. I'll reopen it if I see it again.
Was too hasty closing this one. Ran a battery of tests to be sure. I think I was able to see issue. There was a FetchError eof socket fail when I checked the varnishlog. I'm not sure what it means though since there's no other errors anywhere else. The nginx log is fine and returns a non-empty response.

Now that I have working Docker container. I'm seeing this issue a lot more. It'll be easier to look for a fix.
I've now spent a ton of hours debugging this issue. The only workaround that works is to use return(pipe) instead of return(pass) in the varnish configuration. I've posted about this on the Varnish mailing list. Next step is to create a ticket in the Varnish project itself.
HI i've encountered this also with one of my site. Is the fix available?
This issue is still there. I still haven't written the detailed ticket to the varnish team. Are you getting it constantly?
I actually get it a ton now. The jetpack and redis plugin although function correctly none of the settings pages load for me
HI @carlalexander , I'm getting this issue, and using pipe rather than pass fixes it for me. Did the ticket manage to get posted? Thanks
