I have a really strange white screen problem relating to an specific domain

A blank white page means that PHP is crashing. This problem can be caused by a variety of issues, including: (1) Bad theme (2) Bad plugin (3) Bad install/upgrade (4) you exhausted the memory limit (5) It could also mean that there is an issue with your web hosting server.
– (1) and (2) are more common (typically due to a function conflict introduced by a plugin or theme).
– Since the problem can be caused by any number of things, check the error logs on your server for a more specific error message. If you need help locating them, ask your hosting provider to help you with that.
– If you cannot find error logs or if you don’t find any helpful info in them, try Enabling debugging
– Also, try reviewing this useful article: https://www.ads-software.com/support/article/common-wordpress-errors/#the-white-screen-of-death.

Hey thanks for the reply, I tried most of the things you listed already and just by changing the site domain name to another one it works perfectly. So I think it is unlikely to be a bad theme plugin or memory

Also when applying that domain name to another perfectly working site from my multisite installation, the same issue happens so it has something to do with that specific domain

That’s not really all that strange… PHP appears to be ‘being clobbered’ by something.

Usually a plugin but, in your case, I can see other pages working on that same domain so I don’t think it’s a plugin…

That leaves very little but a theme problem or a function in that theme.

To test this, go to Cloudflare and shut off the Proxy (just click the orange cloud to gray for now). That will let the site serve the homepage if it can but I’m suspicious of the theme there since the problem happens on the first or front-most page.

If I’m right about the theme then the front-most page will die… If it’s the proxied version of the page being blank then shutting Cloudflare off was probably enough to flush that out. You need something to handle cache changes better. I use Cache Enabler if I’m not running a full cache plugin like W3TC.

But I see Elementor there… not that Elementor is bad but Elementor is more powerful so you can break things with it easier, faster, and badder! And I’m thinking something clobbered that Twenty Seventeen theme’s first byte or else a function.

Try swapping the theme for a different ‘Twenties’ Theme or what have you!

Let us know what happens or if you need more help!

I tried purging the Cloudflare cache and changing themes with no result. However today the problem was just suddenly fixed, I have no idea what happened or what the problem was, maybe something was going on with the server, anyways thanks everyone for your answers and support!

Glad its sorted ??
