Strange "white screen until refresh" issue

[Like Ra]

Does anybody else has this issue: if you click on a forum link, most of the time it produces a "white page", and hitting "Refresh" shows the content?

I have no idea what's going on. Any help is greatly appreciated. As always!

It has happen to me too. I would say about 60%.
Yea, I think it started about3-4 days ago.
I thought it might be my phone, but you chimed in, then I knew that others may have the same problem.

The cause??
I think that any time you click on a thread, a routine should automatically refresh the page that you just clicked on.

Now, the question I want to know, is what threads goes blank and which ones don’t.

What happened???

Now when I click on a link, my whole screen goes Black then it jumps to the link.

Never had anything like that happen to me. I'm using Firefox on a few different Linux distros including Ubuntu and EndeavourOS. I do have some plugis: ublock origin, duck duck go privacy essentials and there is PiHole running on my network.

I have seen some server side errors today and yesterday. I don't remember if it was 500 (Internal Server Error) or 503 (Service Unavailable), but check server logs.

No having the problems that have been described and all the links I've tried (from posts and messages) seem to work ok, but...

I am noticing a small 'pause' or delay between the new page being initially presented (a flash of a white screen) and the page being properly displayed. 

I don't recall that happening before.

Ahhhh,,, just tried something - if I select 'open link in new tab' the delay is really noticeable, but it still works.  That is new, and before by the time I went to the new tab the page was aeady open. Interestingly its not a white screen, it's the beige(?) general forum background. 

Also, I'm, apparently, a member of the flat earth society and use Edge - if that's of any use

I noticed it started when we had the attachments issue: https://www.likera.com/forum/mybb/Thread...downloaded

I'm not sure if it's Clowdflare, my changes in Cloudflare, something in the site config, if it's the forum only. OK, let's see ...

I do not know whether it is related, but I also have some 'caching' problems with the dutch teletekst since a number of weeks. And I did have some problems with CNN on my Iphone as well, that it would go back to an old page, every time I would go to its tab. The teletekst problem was that if I wanted to visit for instance page 633 by clicking on a link to it, it would show me the latest old version. I would have to move to the next page, and then back to get the proper version, but there were will ways to go to that page, that would give the old version. To me it looks like an Apple(? or some other system) update, that does not work well together with the way some websites handle caching.

And there are many levels of caching. We got rid of one of then - ModPageSpeed, because it's not supported by CloudFlare. Still, we have PHP, CF, browser (disk and memory) caches.

Morning…
Just tried to click on the Transparent latex button on the forum page and got the white screen.
After waiting for a minute, I hit the refresh, the page came up.
