okay panic over

its fine now.

should i re-add that again in the future when WP updates?

Yeah can you tell me where that file is theres too many to look through

I should probably create a child theme then somehow yes? Once I edit this file, won't there be problems in the future when the theme itself gets updated? I'm not 100% sure where this file is located but ill find it

Oh no it's the entire site in general.

The only reason why I can see my website on my laptop is because i am logged into it on chrome.

However, when I use firefox, where I am not logged into my WP account, it is also blank.

Ohhhhh noooo haha

Hi,

I followed the steps for optimizing speed and, on my laptop, tested it on a speedtest website and received a great score. However, it will not load my website on mobile now whatsoever. I've cleared my cache on the website itself and my mobile browsers history/cookies etc and it's still not doing anything. it's completely white, no error codes, just blank. Not sure if this is related or maybe it's my phone sorry
